The statesman and general Julius Caesar (100-44 B.C.) expanded the Roman Republic through a series of battles across Europe before declaring himself dictator for life. He died famously on the steps of the Senate at the hands of political rivals.
Due to the Social War (91–88 BC), individuals outside Italy were not considered “Roman” and thus were not given full citizenship rights. Caesar started the process to fuse the Roman Empire into a single unit by being generous in granting Roman citizenship to those outside Italy. Like, in 49 BC, all inhabitants of Cisalpine Gaul received Roman citizenship. This process of integrating the Roman Empire was completed by his adopted son and the first Roman Emperor,Augustus. Julius Caesar also regulated and systematized municipal government throughout Italy.
