Messianism is the belief in a messiah, a savior or redeemer. Many religions have a messiah concept, including the Jewish Messiah (from which the term and meaning originates), the Christian Christ (the Greek translation of the Hebrew root word), the Muslim Mahdi and Isa (one of the Arabic names for Jesus), the Buddhist Maitreya, the Hindu Kalki, the Zoroastrian Saoshyant and He whom God shall make manifest in Bábism (believed to be Bahá'u'lláh by Bahais). The state of the world is seen as hopelessly flawed beyond normal human powers of correction, and divine intervention through a specially selected and supported human is seen as necessary.
