'''Gaius Julius Caesar''' (bbirth. [[July 13]], [[100 BC]], ddeath. [[March 15]], [[44 BC]]) was a [[Ancient Rome|Roman]] military and political leader whose conquest of [[Gaul|Gallia Comata]] extended the Roman world all the way to the [[Atlantic Ocean|Oceanus Atlanticus]] and introduced Roman influence into modern [[France]], an accomplishment whose direct consequences are visible to this day. Caesar fought and won a [[civil war]] which left him undisputed master of the Roman world, and began extensive reforms of Roman society and government. His dramatic [[assassin|assassination]] on the [[Roman calendar|Ides of March]] became the catalyst of a second set of civil wars which became the twilight of the [[Roman Republic]] and the dawn of the [[Roman Empire]] under Caesar's grand-nephew and posthumously adopted son, [[Caesar Augustus]]. Caesar's military campaigns are known in detail from his own written ''Commentaries'' (''Commentarii''), and many details of his life are recorded by later historiographers like [[Suetonius|Gaius Suetonius Tranquillus]], [[Plutarch|Mestrius Plutarch]], and [[Dio Cassius|Lucius Cassius Dio]].
