Final answer:
Rome's government evolved from a monarchy to a republic and finally to an empire. These changes were marked by shifts in the balance of power and the way officials were chosen or assumed authority, adapting to Rome's expanding influence and territory.
Step-by-step explanation:
The different types of government that Rome changed through included a monarchy, a republic, and an empire. Initially, Rome was ruled as a monarchy, which saw kings like Romulus and Etruscan rulers such as Tarquin the Proud. Rome transitioned to a republic after a rebellion against the monarchy in 509 BCE, favoring a government where citizens elected leaders like consuls and senators. The republic featured a complex system with the Centuriate Assembly, consuls, and the Senate, all playing crucial roles in governance. The Senate maintained continuous influence from the city's foundation to the fall of the empire. Eventually, Rome became an empire, expanding its territory significantly and modifying its governance structure to manage its vast areas through colonial and municipal levels.
