In response, the Venetian fleet sacked Galata and threatened the imperial palace of Blachernae, but in 1298 they lost again - this time at Curzola.

Doge Gradenigo was responsible for the so-called Serrata del Maggior Consiglio, the "locking" or "closing" of the Great Council of Venice.

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.

[1] He was married first to Tomasina Morosini (with whom he had a daughter, Anna, wife of Jacopo I da Carrara) and then to Agnese Zantani.
