Julius Caesar
Caesar conquered Gaul and became dictator of Rome.
About this topic
Gaius Julius Caesar (100 to 44 BCE) was a brilliant general and politician of the late Roman Republic. He formed the First Triumvirate with Pompey and Crassus, and as governor of Gaul conquered the region between 58 and 50 BCE, gaining wealth, fame and a devoted army; he described it in his own book, Commentaries on the Gallic War.
When the Senate ordered him to disband his army, he crossed the Rubicon River into Italy in 49 BCE, saying the die is cast, which began a civil war against Pompey. After winning, he became dictator, and later dictator for life. He reformed the calendar into the Julian calendar, which is the basis of ours, granted citizenship more widely, helped debtors and began public works.
Many senators feared he would become a king, and on the Ides of March (March 15), 44 BCE, a group led by Brutus and Cassius stabbed him. Instead of saving the Republic, the murder triggered more civil wars, from which his heir Octavian emerged victorious. A misconception is that Caesar was an emperor; he never took that title, but he paved the way. The name Caesar later became a title (kaiser, tsar) for rulers.
