Peter, King of Hungary

Peter Orseolo, or 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 Emperors 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 Pragues reference to his alleged marriage around 1055 suggests that he may also have survived his second deposition.

Peter was born in Venice, the only son of Doge Otto Orseolo. His mother was a sister of Stephen I, the first king of Hungary historian Gyula Krist suggests that he was born in 1010 or 1011. The Venetians rose up and deposed Otto Orseolo in 1026. Peter did not follow his father, who fled to the Byzantine court in Constantinople he instead went to Hungary, where his uncle appointed him commander of the royal army.
