The first triumvirate of the Roman Republic, which consisted of Julius Caesar, Pompey, and Crassus, was simply an alliance or partnership, not a formal institution of the government. The alliance didn't last long, however, and Caesar eventually emerged with total power. This led to his assassination, after which a second triumvirate took over, with Octavian, Mark Antony, and Lepidus dividing the Roman world among themselves. But these triumvirs also soon turned on one another, with Octavian alone taking power; in time he would become Rome's first emperor.
