Monotheism

The word monotheism refers to the worship of a single, all-powerful God. This is characteristic of Judaism, Christianity, and Islam, and is distinct from polytheism, the worship of multiple Gods. Most early religions were polytheistic, like those of ancient Egypt and Greece. The first recorded monotheistic religion was instituted by the pharaoh Akhenaton of Egypt, who led a revolution to replace the multitude of Egyptian deities with a single sun god. Most religions aren't purely monotheistic--Judaism, though monotheistic in nature, did not explicitly deny the existence of other gods; it just rejected the idea of worshiping them. Christianity splits God into three parts (Father, Son, Holy Spirit), but these are all deemed to be part of one over-arching entity.
