Author Description

Religion in ancient Rome encompasses the ancestral ethnic religion of the city of Rome that the Romans used to define themselves as a people, as well as the adopted religious practices of peoples brought under Roman rule. The Romans thought of themselves as highly religious, and attributed their success as a world power to their collective piety (pietas) in maintaining good relations with the gods. According to legends, most of Rome's religious institutions could be traced to its founders, particularly Numa Pompilius, the Sabine second king of Rome, who negotiated directly with the gods. This archaic religion was the foundation of the mos maiorum, "the way of the ancestors" or simply "tradition," viewed as central to Roman identity. As Rome came into contact with foreign cultures, and conquered them, foreign religions increasingly attracted devotees among Romans, who increasingly had ancestry from elsewhere in the Empire. The emperors promoted the Imperial cult around the empire, and this and imported mystery religions were generally practiced alongside the official religion. Ultimately, Roman polytheism was brought to an end with the adoption of Christianity as the official religion of the empire.
