jan 1, 509 BC - Creation of the Roman Republic

Description:

Similarly, as with the creation of the city, later Romans accepted they knew the exact date of the start of the Republic: 509 BC, when the seventh and last ruler of Rome, the overbearing Tarquinius Superbus, was thought to have been expelled by a blue-blooded coup. The Republican process itself was based around the possibility that individually a group of people reserved the privilege to pass laws and choose officers.
