Roman governance evolved from a monarchy to a republic and finally to an empire. Initially, the Roman Kingdom was ruled by kings, but around 509 BCE, the Roman Republic was established, featuring elected officials like consuls and a governing body called the Senate. This system allowed for a balance of power, with citizens participating in decision-making through assemblies. As Rome expanded, the Roman Empire emerged, centralizing authority under an emperor. The emperor held significant power, often supported by a bureaucratic system. Despite this, local governance remained important, with provinces managed by governors who enforced imperial policies while addressing local needs.
