Kaiser

Kaiser is the German word for "emperor". Like the Bulgarian, Serbian and Russian Czar it is directly derived from the Roman emperors' title of Caesar, which in turn is derived from the personal name of a branch of the gens (clan) Julia, to which Gaius Julius Caesar, the forebear of the first imperial family, belonged. Although the British monarchs styled "Emperor of India" were also called "Kaisar-i-Hind" in Hindi and Urdu, this word, although ultimately sharing the same Latin origin, is derived from the (kaisar), not the German Kaiser.
