Polytheism means believing in many gods. A person that believes in polytheism is called a polytheist. A religion with polytheism can be called a polytheistic religion.
Polytheism is well documented in historical religions of classical antiquity, especially those of ancient Greeks and Romans. Other ancient people who were polytheists include German pagans, Ancient Egyptians, the Celts and the Norse.
There are various polytheistic religions practiced today, for example Hinduism, Shintoism, Chinese folk religion, Thelema, Wicca, Druidism, Taoism, Asatru and Candomblé.
Usually, a polytheistic religion has a set of stories about the gods. This is called mythology.
