Peter, King of Hungary

Peter (Hungarian: Velencei Péter, Croatian: Petar iz Venecije, Slovak: Peter z Benátok, Italian: Pietro di Venezia; 1010 or 1011 – 1046, or late 1050s), born Pietro Orseolo and known as Peter the Venetian, was King of Hungary twice. He first succeeded his uncle, King Stephen I, in 1038. His favoritism towards his foreign courtiers caused an uprising which ended with his 1041 deposition. Peter was restored in 1044 by Henry III, Holy Roman Emperor. He accepted the Emperor's suzerainty during his second reign, which ended in 1046 after a pagan uprising. Hungarian chronicles are unanimous that Peter was executed by order of his successor, Andrew I, but the chronicler Cosmas of Prague's reference to his alleged marriage around 1055 suggests that he may also have survived his second deposition.
