The title of the Grand Imam of al-Azhar was officially established in 1961. In the 14th century the head of al-Azhar was granted the title of Mushrif of al-Azhar, then later Nazir of Al-Azhar3 and, during the Ottoman Empire, the Grand Sheikh of al-Azhar. Today the bearer of the title also carries the title of the Grand Sheikh.
