Who Conspired to Kill Julius Caesar?
The plot to assassinate Julius Caesar involved up to 60 men, and the conspiracy was led by Cassius Longinus and Marcus Brutus, Caesar's brother-in-law. Caesar was attacked and stabbed to death on March 15, 44 B.C. as he walked into a meeting of his senate.
Brutus tried to capitalize on the assassination by creating coins that marked the date, often referred to as the Ides of March. He and Cassius Longinus tried to take over the army but had to battle Caesar's adopted son Octavian for control. When their rebel armies were defeated two years after the assassination, Brutus and Longinus both committed suicide.
