What other religion was allowed in Rome?

Answer 1

The Roman Empire allowed for the practice of various religions, including but not limited to:

1. Egyptian religion
2. Greek religion
3. Persian religion
4. Celtic religion
5. Germanic religion
6. Mithraism

However, the Roman Empire was primarily polytheistic, with the official state religion being Roman paganism. The emperors were considered divine and were often deified upon their death, resulting in the worship of imperial cults. While these other religions were allowed to be practiced, they did not have the same status and privileges as the official Roman religion.
