Tribal Assembly
When the city of Rome was founded (traditionally dated at 753 BC), a senate and an assembly, the Curiate Assembly, were both created. The Curiate Assembly was the principal legislative assembly during the era of the Roman Kingdom. While its primary purpose was to elect new kings, it also possessed rudimentary legislative powers. Shortly after the founding of the Roman Republic (traditionally dated to 509 BC), the principal legislative authority shifted to two new assemblies, the Tribal Assembly ("Citizen's Assembly") and the Centuriate Assembly.
