The Seleucid Empire was a Greek power in West Asia during the Hellenistic period. It was founded in 312 BC by the Macedonian general Seleucus I Nicator, following the division of the Macedonian Empire founded by Alexander the Great, and ruled by the Seleucid dynasty until its annexation by the Roman Republic under Pompey in 63 BC.
Bactria, or Bactriana, was an ancient Iranian civilization in Central Asia based in the area south of the Oxus River and north of the mountains of the Hindu Kush, an area within the north of modern Afghanistan. Bactria was strategically located south of Sogdia and the western part of the Pamir Mountains. The extensive mountain ranges acted as protective "walls" on three sides, with the Pamir on the north and the Hindu Kush on south forming a junction with the Karakoram range towards the east.
Year 223 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Flaminus and Philus. The denomination 223 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Antiochus I Soter was a Macedonian king of the Seleucid Empire. Antiochus succeeded his father Seleucus I Nicator in 281 BC and reigned during a period of instability which he mostly overcame until his death on 2 June 261 BC. He is the last known ruler to be attributed the ancient Mesopotamian title King of the Universe.
Antiochus III the Great was a Greek Hellenistic king and the 6th ruler of the Seleucid Empire, reigning from 223 to 187 BC. He ruled over the region of Syria and large parts of the rest of western Asia towards the end of the 3rd century BC. Rising to the throne at the age of eighteen in April/June 223 BC, his early campaigns against the Ptolemaic Kingdom were unsuccessful, but in the following years Antiochus gained several military victories and substantially expanded the empire's territory. His traditional designation, the Great, reflects an epithet he assumed. He also assumed the title Basileus Megas, the traditional title of the Persian kings. A militarily active ruler, Antiochus restored much of the territory of the Seleucid Empire, before suffering a serious setback, towards the end of his reign, in his war against Rome.
Euthydemus Ic. 260 BC – 200/195 BC) was a Greco-Bactrian king and founder of the Euthydemid dynasty. He is thought to have originally been a satrap of Sogdia, who usurped power from Diodotus II in 224 BC. Literary sources, notably Polybius, record how he and his son Demetrius resisted an invasion by the Seleucid king Antiochus III from 209 to 206 BC. Euthydemus expanded the Bactrian territory into Sogdia, constructed several fortresses, including the Derbent Wall in the Iron Gate, and issued a very substantial coinage.
Diodotus I Soter was the first Hellenistic king of Bactria. Diodotus was initially satrap of Bactria, but became independent of the Seleucid empire around 255 BCE, establishing the Greco-Bactrian Kingdom. In about 250 BCE, Diodotus repelled a Parthian invasion of Bactria by Arsaces. He minted an extensive coinage and administered a powerful and prosperous new kingdom. He died around 235 BCE and was succeeded by his son Diodotus II.
Demetrius I Anicetus, also called Damaytra was a Greco-Bactrian and later Indo-Greek king, who ruled areas from Bactria to ancient northwestern India. He was the son of the Greco-Bactrian Kingdom's ruler Euthydemus I and succeeded him around 200 BC, after which he conquered extensive areas in what is now southern Afghanistan, Iran and Pakistan and India.
Mithridates I, also known as Mithridates I the Great, was king of the Parthian Empire from 165 BC to 132 BC. During his reign, Parthia was transformed from a small kingdom into a major political power in the Ancient East as a result of his conquests. He first conquered Aria, Margiana and western Bactria from the Greco-Bactrians sometime in 163–155 BC, and then waged war with the Seleucid Empire, conquering Media and Atropatene in 148/7 BC. In 141 BC, he conquered Babylonia and held an official investiture ceremony in Seleucia. The kingdoms of Elymais and Characene shortly afterwards became Parthian vassals. In c. 140 BC, while Mithridates was fighting the nomadic Saka in the east, the Seleucid king Demetrius II Nicator attempted to regain the lost territories; initially successful, he was defeated and captured in 138 BC, and shortly afterwards sent to one of Mithridates I's palaces in Hyrcania. Mithridates I then punished Elymais for aiding Demetrius, and made Persis a Parthian vassal.
In classical antiquity, the Hellenistic period covers the time in Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII, followed by the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Egypt the following year. The Ancient Greek word Hellas was gradually recognized as the name for Greece, from which the word Hellenistic was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great.
The Indo-Greek Kingdom, or Graeco-Indian Kingdom, also known historically as the Yavana Kingdom (Yavanarajya), was a Hellenistic-era Greek kingdom covering various parts of modern-day Afghanistan, Pakistan and northwestern India. This kingdom was in existence from c. 200 BC to c. 10 AD.
Eucratides I, also called Eucratides the Great, was one of the most important Greco-Bactrian kings. He conquered large parts of northern India, holding territory in the Indus and as far as Barigaza until he was finally defeated by Indo-Greek king Menander. Eucratides minted a vast and prestigious coinage, suggesting a rule of considerable importance and prosperity. His immediate successors were the last Greek kings to rule in Bactria.
Anthimachus I Theos was believed to have been an illegitimate son of Euthydemus, and one of the Greco-Bactrian kings, generally dated from around 185 BC to 170 BC.
Agathocles I Dicaeus was a Greco-Bactrian/Indo-Greek king, who reigned between around 190 and 180 BC, likely of the dynasty of Diodotus I, due to his commemoration of Antiochus Nicator.
Diodotus II Theos was the son and successor of Diodotus I Soter, who rebelled against the Seleucid empire, establishing the Graeco-Bactrian Kingdom. Diodotus II probably ruled alongside his father as co-regent, before succeeding him as sole king around 235 BC. He prevented Seleucid efforts to reincorporate Bactria back into the empire, by allying with the Parthians against them. He was murdered around 225 BC by Euthydemus I, who succeeded him as king.
Dayuan is the Chinese exonym for a country that existed in Ferghana valley in Central Asia, described in the Chinese historical works of Records of the Grand Historian and the Book of Han. It is mentioned in the accounts of the Chinese explorer Zhang Qian in 130 BCE and the numerous embassies that followed him into Central Asia. The country of Dayuan is generally accepted as relating to the Ferghana Valley, controlled by the Hellenistic polis Alexandria Eschate, which can probably be understood as "Greco-Fergana city-state" in English language.
Diomedes Soter or Diodotus was an Indo-Greek king and possible claimant Greco-Bactrian King who may have attempted to reconquer the lands north of the Hindu Kush. The places where his coins have been found seem to indicate that his rule was based in the area of the Paropamisadae, possibly with temporary dominions further east. Judging from their similar portraits and many overlapping monograms, the young Diomedes seems to have been the heir of Philoxenus, the last king to rule before the kingdom of Menander I finally fragmented.
Antiochus Nicator is a proposed Greco-Bactrian king of the Diodotid dynasty, who ruled for some period between 240 – 220 BCE. His existence is controversial.
The Greco-Bactrian Kingdom or simply Greco-Bactria was a Hellenistic-era Greek state, and along with the Indo-Greek Kingdom, the easternmost part of the Hellenistic world in Central Asia and the Indian subcontinent. It was founded in 256 BC by the Seleucid satrap Diodotus I Soter and lasted until its fall c. 120 BC with some cities still controlled by Greek kings such as Hermaeus Soter in what is today Kabul. It was ruled by the Diodotid dynasty and the rival Euthydemid dynasty.
The Euthydemid dynasty was a Hellenistic dynasty founded by Euthydemus I in 230 BC which ruled the Greco-Bactrian and Indo-Greek kingdoms throughout the Hellenistic period from 230 BC to 10 AD, upon the death of its last ruler, Strato III in Gandhara.
