War of the Straits and Sardinian–Aragonese war: The Battle of Alghero results in a crushing victory of the allied Aragonese and Venetian fleet over the Genoese fleet, most of which is captured.

The War of the Straits or Third Genoese–Venetian War was a conflict fought between the Republic of Venice and the Republic of Genoa, and their allies, in 1350–1355. The third in a series of conflicts between the two major Italian maritime republics, the war resulted from the intense commercial and political rivalry over access to the Aegean Sea and the Black Sea. The main immediate events that precipitated the war were the conflicts over Caffa and Tanais in the northern Black Sea, control of passage through the Bosporus straits—whence the conflict received its name—and the seizure of Chios and Phocaea by the Genoese.
