After the Battle of Savra in 1385 the region of Albania became under strong Ottoman influence and gradually most of its territory was annexed to Ottoman Empire within separate administrative unit: the Sanjak of Albania. Andrea revolted against Ottoman rule in 1432 and defeated a small Ottoman military unit in the mountains of Central Albania. His victory inspired other chieftains in Albania, especially Gjergj Arianiti, to rebel against the Ottomans.
