On March 15th, 44 BC a group of senators stabbed Julius Caesar, the dictator of Rome. By his death, they hoped to restore Rome's Republic. Instead, they unleashed a revolution. By December of that year, Rome was plunged into a violent civil war. Three men--Mark Antony, Lepidus, and Octavian--emerged as leaders of a revolutionary regime, which crushed all opposition. In time, Lepidus was removed, Antony and Cleopatra were dispatched, and Octavian stood alone as sole ruler of Rome. He became Augustus, Rome's first emperor, and by the time of his death in AD 14 the 500-year-old republic was but a distant memory and the birth of one of history's greatest empires was complete.
