 In the context of a weakening of Byzantine power in the region following the sack of Constantinople in 1204, Arbanon attained full autonomy under the Despotate of Epirus for 12 years until the death of Demetrios in 1215 or 1216.The Gëziq inscription mentions the Progon family as "judices", and notes their dependence on Vladin and Đorđe Nemanjić (r. 1208–1216), the princes of Zeta.The rulers were also connected to the Serbian Nemanjić dynasty, through marriage and alliances.
