The people of Gades had an alliance with Rome and Julius Caesar bestowed Roman citizenship on all its inhabitants in 49 BC. By the time of Augustus's census, Cádiz was home to more than five hundred "equites" (members of the wealthy upper class), a concentration rivaled only by Patavium (Padua) and Rome itself. It was the principal city of the Roman colony of Augusta Urbs Julia Gaditana. An aqueduct provided fresh water to the town (the island's supply was notoriously bad), running across open sea for its last leg. However, Roman Gades was never very large. It consisted only of the northwest corner of the present island, and most of its wealthy citizens maintained estates outside of it on the nearby island or on the mainland. The lifestyle maintained on the estates led to the Gaditan dancing girls becoming infamous throughout the ancient world.
