Kingdom of Albania (medieval)
The Kingdom of Albania (Albanian: Mbretëria e Arbërisë, Latin: Regnum Albaniae) was established by Charles of Anjou in the Albanian territory he conquered from the Despotate of Epirus in 1271. He took the title of "King of Albania" in February 1272. The kingdom extended from the region of Durrës (then known as Dyrrhachium) south along the coast to Butrint. A major attempt to advance further in direction of Constantinople, failed at the Siege of Berat (1280–1281). A Byzantine counteroffensive soon ensued, which drove the Angevins out of the interior by 1281. The Sicilian Vespers further weakened the position of Charles, and the Kingdom was soon reduced by the Epirotes to a small area around Durrës. The Angevins held out here, however, until 1368, when the city was captured by Karl Thopia. In 1392 Karl Thopia's son surrendered the city and his domains to the Republic of Venice.
History
Background events
During the conflict between the Despotate of Epirus and the Empire of Nicaea in 1253, Gulam of Albania, the leader of Principality of Arbër, was initially allied with Despotate of Epirus. Gulam's troops had occupied the Kostur area trying to prevent the Nicean forces of John Vatatzes from entering Devoll. Vatatzes managed to convince Gulam to switch sides and a new treaty was signed between the parties where John Vatatzes promised to guarantee Gulam's autonomy. The same year the despot of Epirus, Michael II Komnenos Doukas, signed a peace treaty with the Niceans acknowledging their authority over West Macedonia and Albania. The fortress of Krujë was surrendered to Nicean forces. To the city of Krujë, the Nicean Emperor acknowledged the old privileges and also granted new ones. The same privileges were confirmed later by his successor Theodore II Laskaris.
