Julius Caesar Portrait Coin: Gaius Julius Caesar is one of the most famous men in history. At the end of his brilliant military and political career he had gained control of the Roman state. His puppet senate heaped more and more honors upon him. In February 44 B.C. the senate named him dictator for life. Many senators, however, feared that he wished to become king, ending the Republic. On the 15th of March (the Ides of March) 44 B.C., 63 senators, lead by Brutus, attacked him with knives they had hidden in the folds of their togas. This most famous of assassinations plunged the Roman Republic into 17 years of civil war, after which it would re-emerge as the Roman Empire.
