  • Notes 
    • From Wikipedia:

      When [Gradenigo] was elected Doge, he was serving as the podesta? of Capodistria in Istria. Venice suffered a serious blow with the fall of Acre, the last Crusader stronghold in the Holy Land, to the Mamluks of Egypt in 1291. A war between Venice and Genoa began in 1294, and Venice sustained some serious losses: it lost a naval battle, its possessions in Crete were pillaged, and the Byzantine emperor, Andronikos II, arrested many Venetians in Constantinople. In response, the Venetian fleet sacked Galata and threatened the imperial palace of Blachernae, but in 1298 they lost again -- this time at Curzola. Eventually, in 1299 the two republics signed a peace treaty.

      Doge Gradenigo was responsible for the so-called Serrata del Maggior Consiglio, the Locking of the Great Council of Venice. This new law, passed in February 1297, restricted membership of the future Councils only to the descendants of those nobles who were its members between 1293 and 1297. This move created an oligarchic system, disenfranchising a great majority of the citizens and provoking some unrest.

      In 1308, during Gradenigo's reign as doge, Venice became involved in war with the Papacy over the control of Ferrara, and on 27 March 1309 the Republic was excommunicated by Pope Clement V, barring all Christians from trading with Venice. The Doge's policy, seen by many as disastrous, led to a plot to depose him and the Great Council, led by Bajamonte Tiepolo and other members of the aristocratic families. On 15 June 1310, the coup failed and its leaders were severely punished. Tiepolo's plot led to the creation of the Council of Ten, initially as a temporary institution, which later evolved into the permanent body which in reality governed the Republic.

      On 13 August 1311, Gradenigo died, and, since Venice was under interdict and the religious ceremonies could not be held, he was buried in an unmarked grave on Murano.
