Michael, also called Saint Michael the Archangel, Archangel Michael and Saint Michael the Taxiarch is an archangel in Christianity, Judaism, Islam, and the Baháʼí Faith. The earliest surviving mentions of his name are in third- and second-century-BC Jewish works, often but not always apocalyptic, where he is the chief of the angels and archangels, and he is the guardian prince of Israel and is responsible for the care of the people of Israel.
