Hassan al-Banna
In the late 19th century, Jamal-al-Din Afghani, "one of the most influential Muslim reformers" of the era, traveled the Muslim world, advocating for Islamic modernism and pan-Islamism. His sometime acolyte Muhammad Abduh has been called "the most influential figure" of Modernist Salafism. In 1928 Hassan al-Banna established the Muslim Brotherhood, the first mass Islamist organization. Other influential revival activists and thinkers include Rashid Rida and Ali Abdel Raziq.
