Julius Caesar - Dictator of Res publica Romana from 49 BC to 44 BC
Gaius Julius Caesar was a Roman politician and general who played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.

His victories in the Gallic Wars, completed by 51 BC, extended Rome's territory to the English Channel and the Rhine. These achievements granted him unmatched military power. Civil war resulted, and Caesar's victory in the war put him in an unrivalled position of power and influence.

After assuming control of government, he centralised the bureaucracy of the Republic and was eventually proclaimed "dictator in perpetuity", giving him additional authority. But the underlying political conflicts had not been resolved, and on the Ides of March (15 March) 44 BC, Caesar was assassinated by a group of rebellious senators led by Gaius Cassius Longinus, Marcus Junius Brutus, and Decimus Junius Brutus.
