Alvise Sebastiano Mocenigo (1662–1732), sometimes enumeratedAlvise III Mocenigo, was the 112thDoge ofVenice from 1722 to 1732. He was alsoProvveditore Generale (Governor) ofVenetian Dalmatia twice.
Born into one of the most important families (theHouse of Mocenigo) of the Venetian aristocracy, he was a famous Doge of theRepublic of Venice in the 18th century, when the power of Venice started to decline. He dedicated his political life to defending Venetian possessions in the Balkans from theOttoman Empire. When the second Ottomansiege of Corfu occurred in 1716, he was mainly responsible for strengthening Venetian fortifications that successfully resisted the attack.
In 1696 he was namedProvveditore generale di Dalmazia until 1702, then again from 1717 to 1720. During his second tenure, he managed to extendVenetian Dalmatia into the hinterland, taking the areas ofSigno,Imoschi andVrgorac. These gains were confirmed in theTreaty of Passarowitz, and the new border with the Ottoman Empire was namedLinea Mocenigo (Mocenigo Line) after him.[1][2]
Two years later he was elected Doge: he reigned for ten years until his death in 1732.

He is memorialised on a 1728 Venetian monument affixed to the Defensive Wall of the New Fortress of Corfu Town, displaying above the Lion of Saint Mark (the symbol of Venice) and the arms of Diedo.[3] It is inscribed in Latin as follows:
("To God, most good, most great,Alvise III Mocenigo, Duke of the Venetians (i.e.Doge);Marco Antonio Diedo (orMarcantonio Diedo), Supreme Governor (VenetianProvveditore Generale da Mar 1728-31 ("Superintendent General of the Sea"));[3]Giorgio Grimani, Commander of the Fleet; the first ordered this (i.e. the Wall); the second planned it; the third, by labour day and night, quickly completed it").
