Year 100 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Marius and Flaccus (or, less frequently, year 654 Ab urbe condita ). The denomination 100 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.

Roman calendar calendar used by the Roman Kingdom and Roman Republic

The Roman calendar was the calendar used by the Roman kingdom and republic. The term often includes the Julian calendar established by the reforms of the dictator Julius Caesar and emperor Augustus in the late 1st century BC and sometimes includes any system dated by inclusive counting towards months' kalends, nones, and ides in the Roman manner. The term usually excludes the Alexandrian calendar of Roman Egypt, which continued the unique months of that land's former calendar; the Byzantine calendar of the later Roman Empire, which usually dated the Roman months in the simple count of the ancient Greek calendars; and the Gregorian calendar, which refined the Julian system to bring it into still closer alignment with the solar year and is the basis of the current international standard.

<i>Ab urbe condita</i> Ancient Roman year-numbering system

Ab urbe condita, or Anno urbis conditæ, often abbreviated as AUC in either case, is a convention that was used in antiquity and by classical historians to refer to a given year in Ancient Rome. Ab urbe condita literally means "from the founding of the City", while anno urbis conditæ means "in the year since the City's founding". Therefore, the traditional year of the foundation of Rome, 753 BC, would be written AUC 1, while AD 1 would be AUC 754. The foundation of the Empire in 27 BC would be AUC 727.

<i>Anno Domini</i> Western calendar era

The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".



By place

Roman Republic

Consul was the title of one of the two chief magistrates of the Roman Republic, and subsequently also an important title under the Roman Empire. The title was used in other European city states through antiquity and the Middle Ages, then revived in modern states, notably in the First French Republic. The related adjective is consular, from the Latin consularis.

Lucius Valerius Flaccus was a consul of the Roman Republic in 100 BC and princeps senatus during the civil wars of the 80s. He is noted for his peace initiatives, which failed, and for sponsoring the Lex Valeria that created the dictatorship of Sulla.

Gaius Marius Ancient Roman general and statesman

Gaius Marius was a Roman general and statesman. Victor of the Cimbric and Jugurthine wars, he held the office of consul an unprecedented seven times during his career. He was also noted for his important reforms of Roman armies. He was at the centre of a paradigmatic shift from the militia levies of the middle Republic to the professional soldiery of the late Republic; he also developed the pilum, a javelin designed to break on impact, and large-scale changes to the logistical structure of the Roman army.

Asia Minor

Armenia Republic in South Caucasus in West Asia

Armenia, officially the Republic of Armenia, is a country in the South Caucasus region of Eurasia. Located in Western Asia on the Armenian Highlands, it is bordered by Turkey to the west, Georgia to the north, the de facto independent Republic of Artsakh and Azerbaijan to the east, and Iran and Azerbaijan's exclave of Nakhchivan to the south.

Parthia region of north-eastern Iran

Parthia is a historical region located in north-eastern Iran. It was conquered and subjugated by the empire of the Medes during the 7th century BC, was incorporated into the subsequent Achaemenid Empire under Cyrus the Great in the 6th century BC, and formed part of the Hellenistic Seleucid Empire following the 4th-century-BC conquests of Alexander the Great. The region later served as the political and cultural base of the Eastern-Iranian Parni people and Arsacid dynasty, rulers of the Parthian Empire. The Sasanian Empire, the last state of pre-Islamic Persia, also held the region and maintained the Seven Parthian clans as part of their feudal aristocracy.


Deuterocanonical books Books that Catholics and Orthodox accept as part of the canon, but which Protestants do not accept

The deuterocanonical books are books and passages considered by the Catholic Church, the Eastern Orthodox Church and Assyrian Church of the East to be canonical books of the Old Testament but which are considered non-canonical by Protestant denominations. They are books from the Septuagint, the standard translation of the Hebrew Bible in the Hellenistic period, written during the reign of Ptolemy II and referenced extensively in the New Testament, particularly in the Pauline Epistles. With the rise of Rabbinic Judaism at the end of the Second Temple Period, the Hebrew Canon was in flux, until the Masoretic Text, compiled between the 7th and 10th centuries, became the authoritative text of the mainstream Rabbinic Judaism. The Masoretic Text excluded the seven deuterocanonical books and formed the basis for their exclusion in the Protestant Old Testament. The term distinguished these texts both from those that were termed protocanonical books, which were the books of the Hebrew canon; and from the apocryphal books, which were those books of Jewish origin that were known sometimes to have been read in church as scripture but which were considered not to be canonical.

1 Maccabees book

1 Maccabees is a book written in Hebrew by a Jewish author after the restoration of an independent Jewish kingdom by the Hasmonean dynasty, about the latter part of the 2nd century BC. The original Hebrew is lost and the most important surviving version is the Greek translation contained in the Septuagint. The book is held as canonical scripture by the Catholic, Orthodox, and Oriental Orthodox churches, but not by Protestant denominations nor any major branches of Judaism; it is not part of the Tanakh. Such Protestants consider it to be an apocryphal book.

2 Maccabees

2 Maccabees is a deuterocanonical book which focuses on the Maccabean Revolt against Antiochus IV Epiphanes and concludes with the defeat of the Seleucid empire general Nicanor in 161 BC by Judas Maccabeus, the hero of the hard work.

Middle East


Emperor Wu of Han emperor Wu-Ti

Emperor Wu of Han, born Liu Che, courtesy name Tong, was the seventh emperor of the Han dynasty of China, ruling from 141–87 BC. His reign lasted 54 years — a record not broken until the reign of the Kangxi Emperor more than 1,800 years later. His reign resulted in a vast territorial expansion and the development of a strong and centralized state resulting from his governmental reorganization, including his promotion of Confucian doctrines. In the field of historical social and cultural studies, Emperor Wu is known for his religious innovations and patronage of the poetic and musical arts, including development of the Imperial Music Bureau into a prestigious entity. It was also during his reign that cultural contact with western Eurasia was greatly increased, directly and indirectly.

Great Wall of China wall along the historical northern borders of China

The Great Wall of China is the collective name of a series of fortification systems generally built across the historical northern borders of China to protect and consolidate territories of Chinese states and empires against various nomadic groups of the steppe and their polities. Several walls were being built from as early as the 7th century BC by ancient Chinese states; selective stretches were later joined together by Qin Shi Huang (220–206 BC), the first Emperor of China. Little of the Qin wall remains. Later on, many successive dynasties have built and maintained multiple stretches of border walls. The most currently well-known of the walls were built by the Ming dynasty (1368–1644).

The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its logosyllabic script—the most sophisticated and highly developed writing system in pre-Columbian Americas—as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. This region consists of the northern lowlands encompassing the Yucatán Peninsula, and the highlands of the Sierra Madre, running from the Mexican state of Chiapas, across southern Guatemala and onwards into El Salvador, and the southern lowlands of the Pacific littoral plain.

Gaius Servilius Glaucia was a Roman politician who served as praetor in 100 BC. He arranged for the murder of an elected tribune of plebs to make way for Lucius Appuleius Saturninus who had been elected tribune for the next year. While attempting to stand for consul for 99 BC, he was engaged in an exchange between himself and another candidate Gaius Memmius who attempted to prevent his candidature on the grounds that he had not waited the mandatory two years between election as praetor and election to the consulship, as stipulated by the Lex Villia Annalis. In a fit of rage he killed Memmius and fled to the home of one of his supporters, where he committed suicide after Saturninus' riot was suppressed.

  2. There is some dispute over the year of Caesar's birth. Some scholars have made a case for 101 or 102 BC as the year of his birth, based on the dates that he held certain magistracies, but scholarly consensus favors 100 BC. Similarly, some scholars prefer 12 July for the day of his birth, but others give 13 July. Goldsworthy, p. 30, Ward, Heichelheim, & Yeo p. 194.
