when did the roman republic end and why
Roman Republic At home, the Republic similarly experienced a long streak of social and political crises, which ended in several bloody civil wars. At first, the Conflict of the Orders opposed the patricians, the closed oligarchic elite, to the far more numerous plebs, who finally achieved political equality in several steps during the 4th century BC. Later, the vast conquests of the Republic disrupted its society, as the immense influx of slaves they brought enriched the aristocracy, but ruined the peasantry and urban workers. In order to solve this issue, several social reformers, known as the Populares, tried to pass agrarian laws, but the Gracchi brothers, Saturninus, or Clodius Pulcher, were all murdered by their opponents: the Optimates, keepers of the traditional aristocratic order. Mass slavery also caused three Servile Wars; the last of them was lead by Spartacus, a skilful gladiator who ravaged Italy and left Rome powerless until his defeat in 71 BC. In this context, the last decades of the Republic were marked by the rise of great generals, who exploited their military conquests and the factional situation in Rome to gain control of the political system. Marius (between 105-86), then Sulla (between 82-78) dominated in turn the Republic; both used extraordinary powers to purge their opponents. These multiple tensions lead to a series of civil wars; the first between the two generals Julius Caesar and Pompey. Despite his victory and appointment as dictator for life, Caesar was murdered in 44. Caesar's heir Octavian and lieutenant Mark Antony defeated Caesar's assassins Brutus and Cassius in 42, but then turned against each other. The final defeat of Mark Antony and his ally Cleopatra at the Battle of Actium in 31 BC, and the Senate's grant of extraordinary powers to Octavian as Augustus in 27 BC, which effectively made him the first Roman emperor, thus ended the Republic.
