In Shia Islam, the doctrine that a messianic figure (Mahdi) was born, has disappeared, and will one day return; according to Twelvers, this is the 12th Imam, going into Occultation in c. 874

Cause → Event → Consequence
Within early Shia Islam, the death of the eleventh imam Hasan al-Askari in 874 CE without a publicly acknowledged successor created a theological crisis. Shia scholars resolved this by teaching that a twelfth imam had been born but was divinely concealed, preserving the imamate from political persecution by Abbasid authorities.
The doctrine of Occultation (ghayba) emerged as the central eschatological belief of Twelver Shia Islam, asserting that Muhammad al-Mahdi, the twelfth imam and a descendant of the Prophet Muhammad, had been born, then concealed by God, and continues to govern the spiritual affairs of believers from hiding until his destined return.
The doctrine became foundational to Twelver Shia theology and political thought, shaping the role of clerical authority in the imam's absence and fueling enduring messianic expectation across the Muslim world. Belief in the eventual reappearance of the Mahdi remains widespread among both Shia and Sunni Muslims, embedded in canonical religious traditions of both branches.
