Amir al-Mu'minin (Arabic أمير المؤمنين; latinized as Miramolinus, hence Italian Miramolino and Spanish Miramamolín) usually translated Commander of the Faithful or Prince of the Faithful, is the Arabic style of Caliphs and other independent sovereign Muslim rulers that claim legitimacy from a community of Muslims. It has been claimed as the title of rulers in Muslim countries and empires and is still used for some Muslim leaders.
