Incitatus Incitatus Incitatus () was the favored horse of Roman emperor Caligula (reigned 37–41 AD). According to legend, Caligula planned to make him a consul. His name is a Latin adjective meaning "swift" or "at full gallop". According to Suetonius, in the "Lives of the Twelve Caesars" (121 AD), Caligula planned to make Incitatus a consul, and that the horse would "invite" dignitaries to dine with him in a house outfitted with servants there to entertain such events. He also wrote that he had a stable of marble, with an ivory manger, purple blankets, and a collar of precious stones. Cassius
Holy Roman Emperor of Eastern Francia fell within the boundaries of the Holy Roman Empire. The various German princes elected one of their peers as "King of the Germans", after which he would be crowned as emperor by the Pope. After Charles V's coronation, all succeeding emperors were called "elected Emperor" due to the lack of papal coronation, but for all practical purposes, they were simply called "emperors".
