In Abrahamic religions, a messiah or messias (Hebrew: מָשִׁיחַ, Greek: μεσσίας, Arabic: مسيح) is a savior or liberator of a group of people. The concepts of moshiach, messianism, and of a Messianic Age originated in Judaism, and in the Hebrew Bible; a moshiach (messiah) is a king or High Priest traditionally anointed with holy anointing oil, signifying God's approval. Messiahs were not exclusively Jewish: the Book of Isaiah refers to Cyrus the Great, king of the Persian Empire, as a messiah for his decree to rebuild the Temple in Jerusalem.
Ha mashiach (המשיח, 'the Messiah', 'the anointed one'), often referred to as melekh mashiach (מלך המשיח 'King Messiah'), is to be a human leader, physically descended from the paternal Davidic line through King David and King Solomon. He is thought to accomplish predetermined things in only one future arrival, including the unification of the tribes of Israel, the gathering of all Jews to Eretz Israel, the rebuilding of the Temple in Jerusalem, the ushering in of a Messianic Age of global universal peace, and the annunciation of the world to come. Numerous individuals have been purported to be "a" or "the" Jewish Messiah since the fall of the last truly independent Jewish kingdom in the 1st century BCE.
In Christianity, the Messiah is called the Christ, from Greek: χριστός (khristós), translating the Hebrew word of the same meaning. The concept of the Messiah in Christianity originated from the Messiah in Judaism. However, unlike the concept of the Messiah in Judaism, the Messiah in Christianity is the Son of God. Christ became the accepted Christian designation and title of Jesus of Nazareth, because Christians believe that the messianic prophecies in the Old Testament were fulfilled in his mission, death, and resurrection. These specifically include the prophecies of him being descended from the Davidic line, and being declared King of the Jews which happened on the day of his crucifixion. They believe that Christ will fulfill the rest of the messianic prophecies, specifically that he will usher in a Messianic Age and the world to come at his Second Coming.
In Islam, Jesus was a prophet and the Masîḥ (مسيح), the Messiah sent to the Israelites, and he will return to Earth at the end of times, along with the Mahdi, and defeat al-Masih ad-Dajjal, the false Messiah. In Ahmadiyya theology, these prophecies concerning the Mahdi and the second coming of Jesus have been fulfilled in Mirza Ghulam Ahmad (1835–1908), the founder of the Ahmadiyya Movement, and the terms 'Messiah' and 'Mahdi' are synonyms for one and the same person.

After a surprising archaeological discovery at the Temple Mount, renewed questions about the true identity of Messiah became the topic of discussion for Jews, Christians, and Muslims around the world.
