Rome was founded in 753 BC according to legend. Over the next few centuries, Rome was ruled by seven kings and experienced significant growth. The city was situated on seven hills along the Tiber River and had a Mediterranean climate. Around 500 BC, Rome transitioned to a republic as the Etruscan kings were overthrown. Over the following centuries, Rome expanded its territory through military conquests, defeating enemies like the Carthaginians and establishing its dominance over the Italian peninsula and Mediterranean region.
