Overview
Ḥasan ʿAlā Zikrihi's-Salām (Persian/) or Hassan II was the hereditary Imam of the Nizari Isma'ilis of the Alamut Period from 1162 until 1166. From his capital of Alamut he ruled parts of Persia and Syria. His chief subordinate in Syria was Rashid ad-Din Sinan, the Old Man of the Mountain.
Biography
In 1164 Hassan, leading the Nizari sect of Ismaili Islam, proclaimed the Qiyamat, the abrogation of Sharia law. The concept of Qiyamah in exoteric Islam means the End of the World and the Day of Judgment. But in the esoteric interpretations of Ismaili Islam, Qiyamah is the beginning of an era of spiritual renaissance where the spiritual dimensions of Islam will be practiced openly, spiritual truths will become widely known, and certain ritualistic aspects of Islam will be abrogated. Fatimid Ismaili texts from the 10th-11th century describe the anticipated arrival of the Qiyamah era by a future Fatimid Ismaili Imam. These expectations were fulfilled by the declaration of Qiyamah by Imam Hasan.
