John Komnenos Asen

John Komnenos Asen (c. 1305–1363) was a Bulgarian nobleman, son of the despot Stracimir of Kran and brother-in-law of the Serbian tsar Stefan Dušan, whose court he joined. Dušan made him despot and put him in charge of his lands in southern Albania.

From about 1345 he ruled the Principality of Valona, at first as a Serbian vassal. Around 1350–1355 he married Anna Palaiologina, widow of the Epirote despot John II Orsini, which legitimised his standing. After Dušan died in 1355 he sided with the failed Simeon Uroš, yet with Venetian help kept Valona effectively independent.

He had become a Venetian citizen in 1353 and traded with Venice and Ragusa. He probably died of the plague in 1363 and was succeeded by Alexander, likely his son.
