Medieval Bulgarian navy

The Bulgarian fleet took part in successful actions against the Genoese and the Turks with its range reaching Crimea and Trebizond.

The main Bulgarian shipyard was situated in the mouth of the Kamchia river due to the abundance of wood and was burned down when the Turks overran the country.

In 812 Khan Krum used ships to seize several Byzantine fortresses in the Southern Black Sea Coast, most notably Nesebar.

In the beginning of 1257 the Latin Empire hired a fleet of 10 Venetian galleys and on 14 June they captured Nessebar after a short siege but could not achieve anything more.
