He commanded the crusading fleet in the
expedition to Nicopolis in 1396 and also won battles against the
Genoese during the
War of Chioggia of 1378–1381. While he was Venetian
ambassador at
Cremona, he was elected doge (1414), after previously being a procurator of St Mark's basilica, and he had escaped in secret, fearing that he might be held a prisoner by
Gabrino Fondolo, tyrant of that city. He made peace with the
Turkish sultan, but, when hostilities broke out afresh, his fleet defeated that of the Turks at the
Battle of Gallipoli. During his reign, the
patriarch of Aquileia Louis of Teck formed an anti-Venetian alliance with Emperor
Sigismund. Venice, under a double-sided attack, was able to launch an offensive that, in 1419–1420, conquered
Udine,
Cividale,
Feltre,
Belluno and most of
Friuli from the Aquileian patriarchate. The
Cadore also surrendered spontaneously. The ensuing treaty led to a peace with
Hungary and the annexation of the patriarchate's lands to the
Republic of Venice. Mocenigo greatly encouraged commerce, reconstructed the ducal palace and commenced the dogal library. He died after a long illness in 1423. He was interred in the
Basilica di San Giovanni e Paolo, a traditional burial place of the doges. ==See also==
