The Senate of the Roman Kingdom was a political institution in the ancient Roman Kingdom. The word senate derives from the Latin word senex, which means "old man". Therefore, senate literally means "board of old men" and translates as "Council of Elders". The prehistoric Indo-Europeans who settled Rome in the centuries before the legendary founding of Rome in 753 BC were structured into tribal communities. These tribal communities often included an aristocratic board of tribal elders, who were vested with supreme authority over their tribe. The early tribes that had settled along the banks of the Tiber eventually aggregated into a loose confederation, and later formed an alliance for protection against invaders.

The Roman Kingdom, also referred to as the Roman monarchy or the regal period of ancient Rome, was the earliest period of Roman history when the city and its territory were ruled by kings. 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 Republic c. 509 BC.
