Polytheism is opposed to monotheism, since there is not one God, but many Gods. In other words, there is not one transcendent ultimate God, but a series of many Gods. Thus, many ancient religions, like the Greeks and Romans, had a variety of Gods for all occasions. The Israelites were continually fighting against the variety of Baal Gods in Canaan. Many ancient native religions also had a variety of Gods to answer their many questions.
