Romulus was the home of the Romulans, who were an offshoot of the Vulcans. During the late 4th century CE, a group of Vulcans left their homeworld Vulcan and settled the planets Calder II, Dessica II, Draken IV, Yadalla Prime and Barradas III. This civilization, called the Debrune, was regarded as a predecessor of the Romulan Star Empire. After their odyssey, which lasted for centuries, the Vulcans finally reached Romulus, a planet that matched all their needs and seemed as a perfect place to begin a new civilization.
The capital city was Dartha. (ENT novel: The Romulan War: Beneath the Raptor's Wing) The Hall of State was situated in this city, on Romulus. The Imperial Romulan Senate met there in the Senate Chamber.
