title granted by the Ottoman sultan Abdülaziz to the hereditary pasha of Egypt, Ismāʿīl (Ismāʿīl Pasha), in 1867. Derived from a Persian term for “lord” or “ruler,” the title was subsequently used by Ismāʿīl's successors, Tawfīq (Tawfīq Pasha, Muḥammad) and Abbās IIʿ, although it had been used informally by his predecessors before that. It was replaced by the title of sultan in 1914, when Egypt became a British protectorate.
