Pietro Gradenigo

Pietro Gradenigo was a Venetian nobleman and a son of Doge Bartolomeo Gradenigo. He and his brothers owed their advancement to their father's determined lobbying while he was doge, which so angered Venetian opinion that after Bartolomeo's death in 1342 the Major Council banned grants of office to a living doge's relatives.

In 1355 Pietro served the Republic as count of Traù, on the Dalmatian coast that King Louis I of Hungary was contesting with Venice. In 1361, after Doge Giovanni Dolfin's death, he stood for the dogeship himself, but the election went to Lorenzo Celsi.
