A chariot is a type of cart driven by a charioteer, usually using horses [note 1] to provide rapid motive power. The oldest known chariots have been found in burials of the Sintashta culture in modern-day Chelyabinsk Oblast, Russia, dated to c. 1950-1880 BCE   and on cylinder seals from Central Anatolia in Kültepe dated to c. 1900 BCE.  The critical invention that allowed the construction of light, horse-drawn chariots was the spoked wheel.
The chariot was a fast, light, open, two-wheeled conveyance drawn by two or more equids (usually horses) that were hitched side by side, and was little more than a floor with a waist-high guard at the front and sides. It was initially used for ancient warfare during the Bronze and Iron Ages, but after its military capabilities had been superseded by light and heavy cavalries, chariots continued to be used for travel and transport, in processions, for games, and in races.
The word "chariot" comes from the Latin term carrus, a loanword from Gaulish. 
In ancient Rome a biga described a chariot requiring two horses, a triga three, and a quadriga four.
The invention of the wheel used in transportation most likely took place in the Eurasian Steppes of modern-day Russia and Ukraine. Evidence of wheeled vehicles appears from the mid 4th millennium BC near-simultaneously in the Northern Caucasus (Maykop culture), and in Central Europe. These earliest vehicles may have been ox carts.  A necessary precursor to the invention of the chariot is the domestication of animals, and specifically domestication of horses – a major step in the development of civilization. Despite the large impact horse domestication has had in transport and communication, tracing its origins has been challenging.  Evidence supports horses having been domesticated in the Eurasian Steppes, with studies suggesting the Botai culture in modern-day Kazakhstan were the first, about 3500 BCE.  Others say horses were domesticated earlier than 3500 BCE in Eastern Europe (modern Ukraine and Western Kazkhstan), 6000 years ago 
The spread of spoke-wheeled chariots has been closely associated with early Indo-Iranian migrations.  The earliest known chariots have been found in Sintashta culture burial sites, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare.  It is also strongly associated with the ancestors of modern domestic horses, the DOM2 population. (DOM2 horses originated from the Western Eurasia steppes, especially the lower Volga-Don, but not in Anatolia, during the late fourth and early third millennia BCE. Their genes may show selection for easier domestication and stronger backs).  These Aryan people migrated southward into South Asia, ushering in the Vedic period around 1750 BCE. Shortly after this, about 1700 BCE, evidence of chariots appears in Asia-Minor. 
The earliest fully developed spoke-wheeled horse chariots are from the chariot burials of the Andronovo (Timber-Grave) sites of the Sintashta-Petrovka Proto-Indo-Iranian culture in modern Russia and Kazakhstan from around 2000 BCE.  This culture is at least partially derived from the earlier Yamna culture. It built heavily fortified settlements, engaged in bronze metallurgy on an industrial scale, and practiced complex burial rituals reminiscent of Hindu rituals known from the Rigveda and the Avesta . Over the next few centuries, the Andronovo culture spread across the steppes from the Urals to the Tien Shan, likely corresponding to the time of early Indo-Iranian cultures.
Not everyone agrees that the Sintashta culture vehicle finds are true chariots.
In 1996 Joost Crouwel and Mary Aiken Littauer wrote
Let us consider what is actually known of the Sintashta and Krivoe Ozero vehicles. At Sintashta, there remained only the imprints of the lower parts of the wheels in their slots in the floor of the burial chamber; Krivoe Ozero also preserved imprints of parts of the axle and naves. At Sintashta, the wheel tracks and their position relative to the walls of the tomb chamber limited the dimensions of the naves, hence the stability of the vehicle. Ancient naves were symmetrical, the part outside the spokes of equal length to that inside. The present reconstructions of the Sintashta and Krivoe Ozero vehicles above the axle level raise many doubts and questions, but one cannot argue about something for which there is no evidence. It is from the wheel track measurements and the dimensions and positions of the wheels alone that we may legitimately draw conclusions and these are alone sufficient to establish that the Sintashta-Petrovka vehicles would not be manoeuverable enough for use either in warfare or in racing. 
Peter Raulwing and Stefan Burmeister consider the Sintashta and Krivoe Ozero finds from the steppe to be carts rather than chariots.
However, recent discoveries in the Eurasian steppe have provided fresh support to the claim that the chariot originated there, rather than in the Near East itself, and may be attributed to speakers of an Indo-Iranian (or Indo-Aryan) language. In particular, archaeological remains of horse gear and spoked wheeled vehicles have been found at the sites of Sintashta (Russia) and Krivoe Ozero (northern Kazakhstan), with calibrated radiocarbon dating to ca. 2000–1800. These finds, however, provide evidence of a two-wheeled spoked cart that does not fit the definition of the ancient Near Eastern chariot. Before these discoveries can help answer the question of where the chariot originated, thorough studies of the spoked wheeled vehicles and horse gear of the steppes, as well as of interconnections and transfer of knowledge, are necessary (cf. Epimachov and Korjakova in Fansa and Burmeister 2004). 
Chariots figure prominently in Indo-Iranian mythology. Chariots are also an important part of both Hindu and Persian mythology, with most of the gods in their pantheon portrayed as riding them. The Sanskrit word for a chariot is rátha- (m.), which is cognate with Avestan raθa- (also m.), and in origin a substantiation of the adjective Proto-Indo-European *rot-h₂-ó- meaning "having wheels", with the characteristic accent shift found in Indo-Iranian substantivisations. This adjective is in turn derived from the collective noun *rot-eh₂- "wheels", continued in Latin rota, which belongs to the noun *rót-o- for "wheel" (from *ret- "to run") that is also found in Germanic, Celtic and Baltic (Old High German rad n., Old Irish roth m., Lithuanian rãtas m.).  Nomadic tribes of the Pontic steppes, like Scythians such as Hamaxobii, would travel in wagons, carts, and chariots during their migrations.
The oldest testimony of chariot warfare in the ancient Near East is the Old Hittite Anitta text (18th century BCE), which mentions 40 teams of horses (in the original cuneiform spelling: 40 ṢÍ-IM-TI ANŠE.KUR.RAḪI.A) at the siege of Salatiwara. Since the text mentions teams rather than chariots, the existence of chariots in the 18th century BCE is uncertain. The first certain attestation of chariots in the Hittite empire dates to the late 17th century BCE (Hattusili I). A Hittite horse-training text is attributed to Kikkuli the Mitanni (15th century BCE).
The Hittites were renowned charioteers. They developed a new chariot design that had lighter wheels, with four spokes rather than eight, and that held three rather than two warriors. It could hold three warriors because the wheel was placed in the middle of the chariot and not at the back as in Egyptian chariots. Typically one Hittite warrior steered the chariot while the second man was usually the main archer; the third warrior would either wield a spear or sword when charging at enemies or hold up a large shield to protect himself and the others from enemy arrows.
Hittite prosperity largely depended on their control of trade routes and natural resources, specifically metals. As the Hittites gained dominion over Mesopotamia, tensions flared among the neighboring Assyrians, Hurrians, and Egyptians. Under Suppiluliuma I, the Hittites conquered Kadesh and, eventually, the whole of Syria. The Battle of Kadesh in 1274 BCE is likely to have been the largest chariot battle ever fought, involving over 5,000 chariots. 
Models of single axled, solid wheeled, ox drawn vehicles, have been found at several mature Indus Valley cites, such as Chanhudaro, Daimabad, Harappa, and Nausharo,  and are depicted in second millennium BCE Chalcolithic rock art, of the region. 
Spoked-wheeled, horse drawn, chariots, often carrying an armed passenger, are depicted in second millennium BCE Chalcolithic period rock paintings. [note 2] . Examples are know from Chibbar Nulla, Chhatur Bhoj Nath Nulla, and Kathotia.   There are some depictions of chariots among the petroglyphs in the sandstone of the Vindhya range. Two depictions of chariots are found in Morhana Pahar, Mirzapur district. One depicts a biga and the head of the driver. The second depicts a quadriga, with six-spoked wheels, and a driver standing up in a large chariot box. This chariot is being attacked. One figure, who is armed with a shield and a mace, stands in the chariot's path; another figure, who is armed with bow and arrow, threatens the right flank. It has been suggested (speculated) that the drawings record a story, most probably dating to the early centuries BCE, from some center in the area of the Ganges–Yamuna plain into the territory of still Neolithic hunting tribes.  The very realistic chariots carved into the Sanchi stupas are dated to roughly the 1st century.
Bronze Age solid-disk wheel carts were found in 2018 at Sinauli,  which were interpreted by some as horse-pulled "chariots," predating the arrival of the horse-centered Indo-Aryans.   [web 1] [web 2] [web 3] [note 3] They were ascribed by Sanjay Manjul, director of the excavations, to the Ochre Coloured Pottery culture (OCP)/Copper Hoard Culture, which was contemporaneous with the Late Harappan culture, [web 4] [web 1] [note 4] and interpreted by him as horse-pulled chariots. [web 5] [web 1] Majul further noted that "the rituals relating to the Sanauli burials showed close affinity with Vedic rituals, [web 1] and stated that "the dating of the Mahabharata is around 1750 BCE." [web 5] According to Asko Parpola these finds were ox-pulled carts, indicating that these burials are related to an early Aryan migration of Proto-Indo-Iranian speaking people into the Indian subcontinent,  "forming then the ruling elite of a major Late Harappan settlement." 
Horse-drawn chariots, as well as their cult and associated rituals, were spread by the Indo-Iranians,  and horses and horse-drawn chariots were introduced in India by the Indo-Aryans.   
In Rigveda, Indra is described as strong willed, armed with a thunderbolt, riding a chariot:
May the strong Heaven make thee the Strong wax stronger: Strong, for thou art borne by thy two strong Bay Horses. So, fair of cheek, with mighty chariot, mighty, uphold us, strong-willed, thunder armed, in battle. — RigVeda, Book 5, Hymn XXXVI: Griffith 
Among Rigvedic deities, notably the Vedic Sun God Surya rides on a one spoked chariot driven by his charioteer Aruṇa. Ushas (the dawn) rides in a chariot, as well as Agni in his function as a messenger between gods and men.
The Jain Bhagavi Sutra states that Indian troops used a chariot with a club or mace attached to it during the war against the Licchavis during the reign of Ajatashatru of Magadha.  
The Persians succeeded Elam in the mid 1st millennium. They may have been the first to yoke four horses to their chariots. They also used scythed chariots. Cyrus the Younger employed these chariots in large numbers at the Battle of Cunaxa.
Herodotus mentions that the Ancient Libyan and the Ancient Indian (Sattagydia, Gandhara and Hindush) satrapies supplied cavalry and chariots to Xerxes the Great's army. However, by this time, cavalry was far more effective and agile than the chariot, and the defeat of Darius III at the Battle of Gaugamela (331 BCE), where the army of Alexander simply opened their lines and let the chariots pass and attacked them from behind, marked the end of the era of chariot warfare (barring the Seleucid and Pontic powers, India, China, and the Celtic peoples).
Chariots were introduced in the Near East in the 17(18)th–16th centuries BCE.  Some scholars argue that the horse chariot was most likely a product of the ancient Near East early in the 2nd millennium BCE.  Archaeologist Joost Crouwel writes that "Chariots were not sudden inventions, but developed out of earlier vehicles that were mounted on disk or cross-bar wheels. This development can best be traced in the Near East, where spoke-wheeled and horse-drawn chariots are first attested in the earlier part of the second millennium BC..." and were illustrated on a Syrian cylinder seal dated to either the 18th or 17th century BCE. 
Starokorsunskaya kurgan in the Kuban region of Russia contains a wagon grave (or chariot burial) of the Maikop Culture (which also had horses). The two solid wooden wheels from this kurgan have been dated to the second half of the fourth millennium. Soon thereafter the number of such burials in this Northern Caucasus region multiplied.   Linguistic evidence also suggests that the inventors were Indo-European people from Eurasia. 
According to Christoph Baumer, the earliest discoveries of wheels in Mesopotamia come from the first half of the third millennium BCE – more than half a millennium later than the first finds from the Kuban region. At the same time, in Mesopotamia, some intriguing early pictograms of a sled that rests on wooden rollers or wheels have been found. They date from about the same time as the early wheel discoveries in Europe and may indicate knowledge of the wheel. 
The earliest depiction of vehicles in the context of warfare is on the Standard of Ur in southern Mesopotamia, c. 2500 BCE. These are more properly called wagons which were double-axled and pulled by oxen or a hybrid of a donkey and a female onager,  named Kunga in the city of Nagar which was famous for breeding them.  The hybrids were used by the Eblaite,  early Sumerian, Akkadian and Ur III armies.  Although sometimes carrying a spearman with the charioteer (driver), such heavy wagons, borne on solid wooden wheels and covered with skins, may have been part of the baggage train (e.g., during royal funeral processions) rather than vehicles of battle in themselves.
The Sumerians had a lighter, two-wheeled type of cart, pulled by four asses, and with solid wheels. The spoked wheel did not appear in Mesopotamia until the mid second millennium BCE. 
Chariots are frequently mentioned in the Hebrew Tanakh and the Greek Old Testament, respectively, particularly by the prophets, as instruments of war or as symbols of power or glory. First mentioned in the story of Joseph (Genesis 50:9), "Iron chariots" are mentioned also in Joshua (17:16, 18) and Judges (1:19,4:3, 13) as weapons of the Canaanites and Israelites. 1 Samuel 13:5 mentions chariots of the Philistines, who are sometimes identified with the Sea Peoples or early Greeks.
Examples from The Jewish Study Bible  of the Tanakh (Jewish Bible) include:
Examples from the King James Version of the Christian Bible include:
Small domestic horses may have been present in the northern Negev before 3000 BC.  Jezreel (city) has been identified as the chariot base of King Ahab.  And a decorated bronze tablet thought to be the head of a lynchpin of a Canaanite chariot was found at a site that may be Sisera's fortress Harosheth Haggoyim.  
Chariot use made its way into Egypt around 1650 BCE during the Hyksos invasion of Egypt and establishment of the fourteenth dynasty.  In 1659 BCE the Indo-European Hittites sacked Babylon, which demonstrated the superiority of chariots in antiquity. 
The chariot and horse were used extensively in Egypt by the Hyksos invaders from the 16th century BC onwards, though discoveries announced in 2013 potentially place the earliest chariot use as early as Egypt's Old Kingdom (c. 2686–2181 BCE).  In the remains of Egyptian and Assyrian art, there are numerous representations of chariots, which display rich ornamentation. The chariots of the Egyptians and Assyrians, with whom the bow was the principal arm of attack, were richly mounted with quivers full of arrows. The Egyptians invented the yoke saddle for their chariot horses in c. 1500 BCE. As a general rule, the Egyptians used chariots as mobile archery platforms; chariots always had two men, with the driver steering the chariot with his reins while the main archer aimed his bow and arrow at any targets within range. The best preserved examples of Egyptian chariots are the four specimens from the tomb of Tutankhamun. Chariots can be pulled by two or more horses.
As David W. Anthony writes in his book The Horse, the Wheel, and Language , in Eastern Europe, the earliest well-dated depiction of a wheeled vehicle (a wagon with two axles and four wheels) is on the Bronocice pot (c. 3500 BCE). It is a clay pot excavated in a Funnelbeaker settlement in Swietokrzyskie Voivodeship in Poland.  The oldest securely dated real wheel-axle combination in Eastern Europe is the Ljubljana Marshes Wheel (c. 3150 BCE). 
The later Greeks of the first millennium BCE had a (still not very effective) cavalry arm (indeed, it has been argued that these early horseback riding soldiers may have given rise to the development of the later, heavily armed foot-soldiers known as hoplites  ), and the rocky terrain of the Greek mainland was unsuited for wheeled vehicles.The chariot was heavily used by the Mycaenean Greeks, most probably adopted from the Hittites, around 1600 BC. Linear B tablets from Mycenaean palaces record large inventories of chariots, sometimes with specific details as to how many chariots were assembled or not (i.e. stored in modular form).On a gravestone from the royal Shaft-grave V in Mycenae dated LH II (about 1500 BC) there is one of the earliest depiction of the chariot in Achaean art. This sculpture shows a single man driving a two-wheeled small box chariot. Later the vehicles were used in games and processions, notably for races at the Olympic and Panathenaic Games and other public festivals in ancient Greece, in hippodromes and in contests called agons . They were also used in ceremonial functions, as when a paranymph , or friend of a bridegroom, went with him in a chariot to fetch the bride home.
Herodotus (Histories, 5. 9) Reports that chariots were widely used in the Pontic–Caspian steppe by the Sigynnae.
Greek chariots were made to be drawn by two horses attached to a central pole. If two additional horses were added, they were attached on each side of the main pair by a single bar or trace fastened to the front or prow of the chariot, as may be seen on two prize vases in the British Museum from the Panathenaic Games at Athens, Greece, in which the driver is seated with feet resting on a board hanging down in front close to the legs of the horses. The biga itself consists of a seat resting on the axle, with a rail at each side to protect the driver from the wheels. Greek chariots appear to have lacked any other attachment for the horses, which would have made turning difficult.
The body or basket of the chariot rested directly on the axle (called beam) connecting the two wheels. There was no suspension, making this an uncomfortable form of transport. At the front and sides of the basket was a semicircular guard about 3 ft (1 m) high, to give some protection from enemy attack. At the back the basket was open, making it easy to mount and dismount. There was no seat, and generally only enough room for the driver and one passenger.
The reins were mostly the same as those in use in the 19th century, and were made of leather and ornamented with studs of ivory or metal. The reins were passed through rings attached to the collar bands or yoke, and were long enough to be tied round the waist of the charioteer to allow for defense.
The wheels and basket of the chariot were usually of wood, strengthened in places with bronze or iron. The wheels had from four to eight spokes and tires of bronze or iron. Due to the widely spaced spokes, the rim of the chariot wheel was held in tension over comparatively large spans. Whilst this provided a small measure of shock absorption, it also necessitated the removal of the wheels when the chariot was not in use, to prevent warping from continued weight bearing.  Most other nations of this time had chariots of similar design to the Greeks, the chief differences being the mountings.
According to Greek mythology, the chariot was invented by Erichthonius of Athens to conceal his feet, which were those of a dragon. 
The most notable appearance of the chariot in Greek mythology occurs when Phaëton, the son of Helios, in an attempt to drive the chariot of the sun, managed to set the earth on fire. This story led to the archaic meaning of a phaeton as one who drives a chariot or coach, especially at a reckless or dangerous speed. Plato, in his Chariot Allegory , depicted a chariot drawn by two horses, one well behaved and the other troublesome, representing opposite impulses of human nature; the task of the charioteer, representing reason, was to stop the horses from going different ways and to guide them towards enlightenment.
The Greek word for chariot, ἅρμα, hárma, is also used nowadays to denote a tank, properly called άρμα μάχης, árma mákhēs, literally a "combat chariot".
The Trundholm sun chariot is dated to c. 1400 BCE (see: Nordic Bronze Age). The horse drawing the solar disk runs on four wheels, and the Sun itself on two. All wheels have four spokes. The "chariot" comprises the solar disk, the axle, and the wheels, and it is unclear whether the sun is depicted as the chariot or as the passenger. Nevertheless, the presence of a model of a horse-drawn vehicle on two spoked wheels in Northern Europe at such an early time is astonishing.
In addition to the Trundholm chariot, there are numerous petroglyphs from the Nordic Bronze Age that depict chariots. One petroglyph, drawn on a stone slab in a double burial from c. 1000 BCE, depicts a biga with two four-spoked wheels.
The use of the composite bow in chariot warfare is not attested in northern Europe.
The Celts were famous for their chariots and modern English words like car, carriage and carry are ultimately derived from the native Brythonic language (Modern Welsh: Cerbyd). The word chariot itself is derived from the Norman French charriote and shares a Celtic root (Gaulish: karros). Some 20 iron-aged chariot burials have been excavated in Britain, roughly dating from between 500 BCE and 100 BCE. Virtually all of them were found in East Yorkshire – the exception was a find in 2001 in Newbridge, 10 km west of Edinburgh.
The Celtic chariot, which may have been called karbantos in Gaulish (compare Latin carpentum),   was a biga that measured approximately 2 m (6 ft 6+3⁄4 in) in width and 4 m (13 ft 1+1⁄2 in) in length.
British chariots were open in front. Julius Caesar provides the only significant eyewitness report of British chariot warfare:
Their mode of fighting with their chariots is this: firstly, they drive about in all directions and throw their weapons and generally break the ranks of the enemy with the very dread of their horses and the noise of their wheels; and when they have worked themselves in between the troops of horse, leap from their chariots and engage on foot. The charioteers in the meantime withdraw some little distance from the battle, and so place themselves with the chariots that, if their masters are overpowered by the number of the enemy, they may have a ready retreat to their own troops. Thus they display in battle the speed of horse, [together with] the firmness of infantry; and by daily practice and exercise attain to such expertness that they are accustomed, even on a declining and steep place, to check their horses at full speed, and manage and turn them in an instant and run along the pole, and stand on the yoke, and thence betake themselves with the greatest celerity to their chariots again. 
Chariots play an important role in Irish mythology surrounding the hero Cú Chulainn.
Chariots could also be used for ceremonial purposes. According to Tacitus ( Annals 14.35), Boudica, queen of the Iceni and a number of other tribes in a formidable uprising against the occupying Roman forces, addressed her troops from a chariot in 61:
The last mention of chariot use in battle seems to be at the Battle of Mons Graupius, somewhere in modern Scotland, in 84 CE. From Tacitus ( Agricola 1.35–36) "The plain between resounded with the noise and with the rapid movements of chariots and cavalry." The chariots did not win even their initial engagement with the Roman auxiliaries: "Meantime the enemy's cavalry had fled, and the charioteers had mingled in the engagement of the infantry."
Later through the centuries, the chariot was replaced by the "war wagon". The "war wagon" was a medieval development used to attack rebel or enemy forces on battle fields. The wagon was given slits for archers to shoot enemy targets, supported by infantry using pikes and flails and later for the invention of gunfire by hand-gunners; side walls were used for protection against archers, crossbowmen, the early use of gunpowder and cannon fire.
It was especially useful during the Hussite Wars, c. 1420, by Hussite forces rebelling in Bohemia. Groups of them could form defensive works, but they also were used as hardpoints for Hussite formations or as firepower in pincer movements. This early use of gunpowder and innovative tactics helped a largely peasant infantry stave off attacks by the Holy Roman Empire's larger forces of mounted knights.
The only intact Etruscan chariot dates to c. 530 BCE and was uncovered as part of a chariot burial at Monteleone di Spoleto. Currently in the collection of the Metropolitan Museum of Art,  it is decorated with bronze plates decorated with detailed low-relief scenes, commonly interpreted as depicting episodes from the life of Achilles. 
In Urartu (860–590 BC), the chariot was used by both the nobility and the military. In Erebuni (Yerevan), King Argishti of Urartu is depicted riding on a chariot which is pulled by two horses. The chariot has two wheels and each wheel has about eight spokes. This type of chariot was used around 800 BCE.
In the Roman Empire, chariots were not used for warfare, but for chariot racing, especially in circuses, or for triumphal processions, when they could be pulled by as many as ten horses or even by dogs, tigers, or ostriches[ citation needed ]. There were four divisions, or factiones, of charioteers, distinguished by the colour of their costumes: the red, blue, green and white teams. The main centre of chariot racing was the Circus Maximus,  situated in the valley between the Palatine and Aventine Hills in Rome. The track could hold 12 chariots, and the two sides of the track were separated by a raised median termed the spina. Chariot races continued to enjoy great popularity in Byzantine times, in the Hippodrome of Constantinople, even after the Olympic Games had been disbanded, until their decline after the Nika riots in the 6th century.  The starting gates were known as the Carceres.
An ancient Roman car or chariot pulled by four horses abreast together with the horses pulling it was called a Quadriga , from the Latin quadriugi (of a team of four). The term sometimes meant instead the four horses without the chariot or the chariot alone. A three-horse chariot, or the three-horse team pulling it, was a triga, from triugi (of a team of three). A two-horse chariot, or the two-horse team pulling it, was a biga, from biugi.
A popular legend that has been around since at least 1937 traces the origin of the 4 ft 8+1⁄2 in standard railroad gauge to Roman times,  suggesting that it was based on the distance between the ruts of rutted roads marked by chariot wheels dating from the Roman Empire. [note 11] This is encouraged by the fact that the otherwise peculiar distance is almost exactly 5 Roman feet but there is no evidence to span the millennium and a half between the departure of the Romans from Britain and the adoption of the gauge on the Stockton and Darlington Railway in 1825.
The earliest archaeological evidence of chariots in China, a chariot burial site discovered in 1933 at Hougang, Anyang in Henan province, dates to the rule of King Wu Ding of the late Shang Dynasty (c. 1250 BCE). Oracle bone inscriptions suggest that the western enemies of the Shang used limited numbers of chariots in battle, but the Shang themselves used them only as mobile command-vehicles and in royal hunts. 
During the Shang Dynasty, members of the royal family were buried with a complete household and servants, including a chariot, horses, and a charioteer. A Shang chariot was often drawn by two horses, but four-horse variants are occasionally found in burials.
Jacques Gernet claims that the Zhou dynasty, which conquered the Shang ca. 1046 BCE, made more use of the chariot than did the Shang and "invented a new kind of harness with four horses abreast".  The crew consisted of an archer, a driver, and sometimes a third warrior who was armed with a spear or dagger-axe. From the 8th to 5th centuries BCE the Chinese use of chariots reached its peak. Although chariots appeared in greater numbers, infantry often defeated charioteers in battle.
Massed-chariot warfare became all but obsolete after the Warring-States Period (476–221 BCE). The main reasons were increased use of the crossbow, use of long halberds up to 18 feet (5.49 m) long and pikes up to 22 feet (6.71 m) long, and the adoption of standard cavalry units, and the adaptation of mounted archery from nomadic cavalry, which were more effective. Chariots would continue to serve as command posts for officers during the Qin dynasty (221–206 BCE) and the Han Dynasty (206 BCE–220 CE), while armored chariots were also used during the Han Dynasty against the Xiongnu Confederation in the Han–Xiongnu War (133 BC to 89 CE), specifically at the Battle of Mobei (119 BCE).
Before the Han Dynasty, the power of Chinese states and dynasties was often measured by the number of chariots they were known to have. A country of a thousand chariots ranked as a medium country, and a country of ten thousand chariots ranked as a huge and powerful country.  
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
The 2nd millennium BC spanned the years 2000 BC to 1001 BC. In the Ancient Near East, it marks the transition from the Middle to the Late Bronze Age. The Ancient Near Eastern cultures are well within the historical era: The first half of the millennium is dominated by the Middle Kingdom of Egypt and Babylonia. The alphabet develops. At the center of the millennium, a new order emerges with Mycenaean Greek dominance of the Aegean and the rise of the Hittite Empire. The end of the millennium sees the Bronze Age collapse and the transition to the Iron Age.
A number of hypotheses exist on many of the key issues regarding the domestication of the horse. Although horses appeared in Paleolithic cave art as early as 30,000 BCE, these were wild horses and were probably hunted for meat.
A spoke is one of some number of rods radiating from the center of a wheel, connecting the hub with the round traction surface.
The Nordic Bronze Age is a period of Scandinavian prehistory from c. 2000/1750–500 BC.
The Andronovo culture is a collection of similar local Late Bronze Age cultures that flourished c. 2000–1150 BC, in eastern Central Asia, spanning from the southern Urals to the upper Yenisei River in central Siberia. Some researchers have preferred to term it an archaeological complex or archaeological horizon. The slightly older Sintashta culture, formerly included within the Andronovo culture, is now considered separately to Early Andronovo cultures. New research shows Andronovo culture's first stage could have begun at the end of the 3rd millennium BC, with cattle grazing, as natural fodder was by no means difficult to find in the pastures close to dwellings.
Chariot burials are tombs in which the deceased was buried together with their chariot, usually including their horses and other possessions. An instance of a person being buried with their horse is called horse burial.
The Srubnaya culture, also known as Timber-grave culture, was a Late Bronze Age 1900–1200 BC culture in the eastern part of Pontic–Caspian steppe. It is a successor of the Yamna culture, Catacomb culture and Poltavka culture. It is co-ordinate and probably closely related to the Andronovo culture, its eastern neighbor. Whether the Srubnaya culture originated in the east, west, or was a local development, is disputed among archaeologists.
The Catacomb culture was a Bronze Age culture which flourished on the Pontic steppe in 2500–1950 BC.
The Abashevo culture is a late Middle Bronze Age archaeological culture, ca. 2200–1850 BC, found in the valleys of the middle Volga and Kama River north of the Samara bend and into the southern Ural Mountains. It receives its name from the village of Abashevo in Chuvashia.
Sintashta is an archaeological site in Chelyabinsk Oblast, Russia. It is the remains of a fortified settlement dating to the Bronze Age, c. 2800–1600 BC, and is the type site of the Sintashta culture. The site has been characterised "fortified metallurgical industrial center".
The Anatolians were Indo-European-speaking peoples of the Anatolian Peninsula in present-day Turkey, identified by their use of the Anatolian languages. These peoples were among the oldest Indo-European ethnolinguistic groups and one of the most archaic, because Anatolians were among the first Indo-European peoples to separate from the Proto-Indo-European community that gave origin to the individual Indo-European peoples.
Ratha is also known as the Indo-Iranian term for a spoked-wheel chariot or a cart of antiquity.
The first depictions of four-wheeled wagons pulled by semi-domesticated onagers and other available animals come from the Sumerians.
In ancient Egyptian society chariotry stood as an independent unit in the King’s military force. Chariots are thought to have been first used as a weapon in Egypt by the Hyksos in the 16th century BC. The Egyptians then developed their own chariot design.
The Horse, the Wheel, and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World is a 2007 book by the anthropologist David W. Anthony, in which the author describes his "revised Kurgan theory." He explores the origins and spread of the Indo-European languages from the Pontic–Caspian steppe throughout Western Europe, Central Asia, and South Asia. He shows how the domesticated horse and the invention of the wheel mobilized the steppe herding societies in the Eurasian Steppe, and combined with the introduction of bronze technology and new social structures of patron-client relationships gave an advantage to the Indo-European societies. The book won the Society for American Archaeology's 2010 Book Award.
The Sintashta culture is a Middle Bronze Age archaeological culture of the Southern Urals, dated to the period c. 2200–1900 BCE. It is the first phase of the Sintashta–Petrovka complex, c. 2200–1750 BCE. The culture is named after the Sintashta archaeological site, in Chelyabinsk Oblast, Russia, and spreads through Orenburg Oblast, Bashkortostan, and Northern Kazakhstan. The Sintashta culture is thought to represent an eastward migration of peoples from the Corded Ware culture. It is widely regarded as the origin of the Indo-Iranian languages The earliest known chariots have been found in Sintashta burials, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare. Sintashta settlements are also remarkable for the intensity of copper mining and bronze metallurgy carried out there, which is unusual for a steppe culture. Among the main features of the Sintashta culture are high levels of militarism and extensive fortified settlements, of which 23 are known.
The ancient Chinese chariot was used as an attack and pursuit vehicle on the open fields and plains of ancient China from around 1200 BCE. Chariots also allowed military commanders a mobile platform from which to control troops while providing archers and soldiers armed with dagger-axes increased mobility. They reached a peak of importance during the Spring and Autumn period, but were largely superseded by cavalry during the Han Dynasty.
Sinauli is an archaeological site in western Uttar Pradesh, India, at the Ganga-Yamuna Doab. The site gained attention for its Bronze Age solid-disk wheel carts, found in 2018, which were interpreted by some as horse-pulled "chariots".
The Indo-European migrations were hypothesized migrations of Proto-Indo-European language (PIE) speakers, and subsequent migrations of people speaking derived Indo-European languages, which took place approx. 4000 to 1000 BCE, potentially explaining how these languages came to be spoken across a large area of Eurasia, spanning from the Indian subcontinent and Iranian plateau, till the European subcontinent.
