John III Doukas Vatatzes
During the conflicts between Michael II Komnenos Doukas of Epirus and Emperor John III Doukas Vatatzes, Golem (ruler of Arbanon at the time) and Theodore Petraliphas, who were initially Michael's allies, defected to John III in 1252. He is last mentioned in the sources among other local leaders, in a meeting with George Akropolites in Durrës in 1256. Arbanon was a beneficiary of the Via Egnatia trade road, which brought wealth and benefits from the more developed Byzantine civilization.
