"Pietro Gradenigo (1251 – 13 August 1311) was the 49th Doge of Venice, reigning from 1289 to his death.
When he was elected Doge, he was serving as the podestà 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." - (en.wikipedia.org 22.06.2020)
