Louis of Durazzo
Louis of Durazzo (1324–1362), Count of Gravina, was the younger brother of Charles, Duke of Durazzo. Made Vicar- and Captain-General of Albania in 1337, he married Margaret of Sanseverino in 1343 and rose with the Durazzo faction at Joanna I's court.
In 1348 Louis I of Hungary invaded and had Charles executed; Louis was imprisoned with his younger brother Robert until 1352. He spent his remaining years stirring up revolts against Joanna in Apulia with Free Company mercenaries.
In 1360 Louis of Taranto crushed them and shut him in the Castel dell'Ovo at Naples, where he was poisoned on 22 July 1362. His son by Margaret became Charles III of Naples.
