Gaius Julius Caesar,often simply referred to as Julius Caesar,was a Roman military and political leader and one of the most influential men in world history.He played a critical role in the transformation of the Roman Republic into the Roman Empire.His conquest of Gaul extended the Roman world all the way to the Atlantic Ocean,and he was also responsible for the first Roman invasion of Britain in 55 BC.
Leading his legions across Rubicon,Caesar sparked civil war in 49 BC that left him the undisputed master of the Roman world.After assuming control of the government,he began extensive reforms of Roman society and government.He was proclaimed dictator for life,and he heavily centralized the bureaucracy of the Republic.This forced the hand of a friend of Caesar,Marcus Junius Brutus,who then conspired with others to murder the dictator and restore the Republic.This dramatic assassination occurred on the Ides of March (March 15th) in 44 BC and led to another Roman civil war.In 42 BC,two years after his assassination,the Roman Senate officially sanctified him as one of the Roman deities.
Caesar's military campaigns are known in detail from his own written Commentaries (Commentarii),and many details of his life are recorded by later historians,such as Appian,Suetonius,Plutarch,Cassius Dio and Strabo.Other information can be gleaned from other contemporary sources,such as the letters and speeches of Caesar's political rival Cicero,the poetry of Catullus and the writings of the historian Sallust.
