The Senatus Imperia (Eng: Imperial Senate) is the bicameral, democratic legislature of the Roman Empire, consisting of the Curiate Assembly, its lower house, and the Consular Congress, its upper house. It embodies Senatus Populusque Romanus, the sovereignty of the people of Rome. Some of the most powerful men in the world assemble in its name inside the Senatus in Rome. Upper House is called the Comitium Consularis (Consular Congress), a body of 40 consules who represent the Imperium's major cultural groups. The first and most powerful consul is the Consul Italii, elected leader of the Romans.
