In 1961, Nasser sought to firmly establish Egypt as the leader of the Arab world and to promote a second revolution in Egypt with the purpose of merging Islamic and socialist thinking. To achieve this, he initiated several reforms to modernize al-Azhar, which serves as the de facto leading authority in Sunni Islam, and to ensure its prominence over the Muslim Brotherhood and the more conservative Wahhabism promoted by Saudi Arabia. Nasser had used al-Azhar's most willing ulema (scholars) as a counterweight to the Brotherhood's Islamic influence, starting in 1953.
