Messianism is the belief in the advent of a messiah who acts as the savior of a group of people. Messianism originated as a Zoroastrianism religious belief and followed to Abrahamic religions, but other religions have messianism-related concepts. Religions with a messiah concept include Judaism (Mashiach), Christianity (Christ), Islam (Isa Masih), Druze faith (Jesus and Hamza ibn Ali), Zoroastrianism (Saoshyant), Buddhism (Maitreya), Taoism (Li Hong), and Bábism (He whom God shall make manifest).
In Judaism, the messiah will be a future Jewish king from the line of David and redeemer of the Jewish people and humanity. In Christianity, Jesus is the messiah, the savior, the redeemer, and God. In Islam, Jesus was a prophet and the messiah of the Jewish people who will return in the end times.
