It was the Republic.  The senators failed to gain the support of the Roman people of killing Julius Caesar and a power struggle took place where all the armies of the Republic were defeated by Mark Anthony, Octavian and Lepidus at the Battle of Philippi in 42 B.C. Later Anthony and Octavian fought at Actium where Anthony and Cleopatra were defeated and took their own lives.  Octavian’s victory marked the end of the Republic and the start of the Empire of Rome where he was give the name Augustus.

When Caesar Augustus came to power in Rome, the Republic came to an end. The Roman Republic was a worn-out institution, where civil wars and dictatorships had worn away the power and credibility of the Senate. Governance was impossible. When Caesar Octavianus (his original name), who had already been part of an earlier dictatorship called the Second Triumvirate, assumed as Consul, the Senate (pressured by Roman society, which esteemed him from his dictatorial era) granted him the sum of public power and the title of Augustus. In this way, the transition of the Republic to the Roman Empire occurred, being Caesar Augustus the first Roman emperor.
