The state council of the ancient Roman republic and empire, which shared legislative power with the popular assemblies, administration with the magistrates, and judicial power with the knights.
A senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate (Latin: Senatus), so-called as an assembly of the senior (Latin: senex meaning “the elder” or “old man”) and therefore allegedly wiser and more experienced members of the society or ruling class. Thus, the literal meaning of the word “senate” is Assembly of Elders.
