100 BC

From Wikipedia, the free encyclopedia

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) and the First Year of Tianhan. 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.

  4. ^ 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. For a source arguing for 12 July, see Badian in Griffin (ed.) p.16
