Where did global Islam come from? “Islam in the Age of Empire, Steam, and Print” looks at the period between 1870 and 1920, when the infrastructure of empire combined with technology to create the conditions needed for global Islam. Starting with the Ottoman Empire’s call for worldwide Muslim unity against European colonizers, journals and magazines with worldwide subscriptions spread messages of Islam. Salafism, developed by Rashid Rida (d. 1935), rejected ritual and miracles, combining modern science with the teachings of the Prophet Muhammad. Global Islam lost some of its focus when the Ottoman Empire collapsed shortly after the First World War.
