Messianism

Messianism is the belief in the advent of a Messiah who acts as the savior of a group of people. Messianism originated as a Zoroastrian religious belief and followed to Abrahamic religions, but other religions also have messianism-related concepts. Religions with a Messiah concept include Hinduism, Judaism, Christianity, Islam, Druze faith, Zoroastrianism, Buddhism, Taoism, and Babism.
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 of God. In Islam, Jesus was a prophet and the Messiah of the Jewish people who will return in the end times.
