Orio Mastropiero (1150–1192)
Born 1150 CE, died 1192 CE.
Orio Mastropiero (died 13 June 1192), forename sometimes rendered as Aurio and surname as Malipiero, was a Venetian statesman who served as the Doge of Venice from 1178 to 1192. He was elected by the Council of Forty in 1178 following the retirement of Sebastiano Ziani. Prior to this he had been an ambassador to Sicily in 1175, tasked with drawing up a treaty with King William II. He had also been the electors' first choice for doge following the death of Vitale II Michiel in 1172, but stepped aside in favour of Ziani, an older and wealthier man. His time in office was mostly unremarkable, apart from a revolt against Venetian rule in Zara, supported by King Béla III of Hungary. For a long while Venice remained passive, being in financial difficulty, but took action at last in 1187 or 1188 when, having secured loans from the Venetian nobility, Mastropiero launched a siege against the Zaratines.
