Caesar was stabbed (23 times) to death in the Roman Senate by a group of conspirators led by Marcus Junius Brutus and Gaius Cassius Longinus. His death marks a turning point in Roman history. Some Romans celebrate the Ides of March as new year celebrations. In Canada, the day is celebrated with the drinking of Bloody Caesars.
