How it ended, as its article says

Dissolved, -0509. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

According to tradition, the Roman Kingdom began with the city's founding c. 753 BC, with settlements around the Palatine Hill along the river Tiber in central Italy, and ended with the overthrow of the kings and the establishment of the Roman Republic c. 509 BC.
