All Christian religions and Islam are both prominent examples of monotheism. Monotheism is the belief in only one god. The opposite to monotheism is polytheism, or the belief in many gods. Most pagan religions (such as the Greeks, Romans, Aztec/Maya/Inca etc, and some Australian Aborigines) were polytheistic. Shinto, Buddhist and several 'cult' religions (amongst others) are polytheistic today.
