Ancient Roman Religion

The Romans borrowed heavily from the Greeks for their mythology,
yet they did develop some of their own myths and gods. The early Roman religion
consisted of worshiping nature gods. As the Roman Empire expanded, the Romans
borrowed from the Greeks, Egyptians, and Persians. For example, the Egyptian goddess
Isis had a temple in Rome. The Persian god Mithras became very popular among the
armies of Rome. During the empire period, the emperor himself was worshipped as
a god. This worship brought them into conflict with the new religion of Christianity,
which became the dominant religion toward the end of the empire.
