Why was "tantrum" trending last week?
Turkish viceroy of Egypt, 1867, from French khédive, from Turkish khidiv, from Persian khidiw "prince," derivative of khuda "master, prince," from Old Persian khvadata- "lord," from compound *khvat-data-, literally "created from oneself," from khvat- (from PIE *swe-tos "from oneself," ablative of root *s(w)e-; see idiom) + data- "created."
title granted by the Ottoman sultan Abdulaziz to the hereditary pasha of Egypt, Isma'il, in 1867. Derived from a Persian term for "lord" or "ruler," the title was subsequently used by Isma'il's successors, Tawfiq and 'Abbas II, 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.
