Andronikos Asen

Andronikos Asen (c. 1279–c. 1322) was the son of Tsar Ivan Asen III of Bulgaria and Irene Palaiologina, sister of Emperor Andronikos II. After his parents fled to Byzantium in 1280, he entered imperial service, and in 1316 the emperor named him governor of the province in the Morea.

Exploiting strife within the Frankish Principality of Achaea, he conquered much of the central Morea and in 1320 seized Akova, Karytaina and Saint George, defeating a Frankish army in September. He died about 1322; his daughter Irene married the future emperor John VI Kantakouzenos.
