In the spring of 1432, after the first phase of the reforms ended, an Albanian revolt erupted which spread to much of Albania. The first revolts began in central Albania when Andrea Thopia revolted against Ottoman rule and defeated a small Ottoman unit in the mountains of central Albania. His victory inspired other chieftains to revolt, especially Arianiti. Gjergj was at first apprehensive, but saw an opportunity to save the dominions left to him by his father. Upon hearing of the rebellions, many Albaniab political enemies of Gjergj, who had become "sipahi" returned from Edirne to Albania. Upon reaching Albania, Gjergj immediately banished them. He was to lead the armed rebellion, which was started by the peasants. Durrës, the Tirana region, and Nicholas Dukagjini in the north joined the revolt. Although Skanderbeg was summoned home by his relatives when Gjergj Arianiti and other chiefs from the region between Vlorë and Shkodër had organized the rebellion, Skanderbeg did nothing, remaining loyal to the Sultan. The Porte responded by sending an army of fresh troops in Albania under experienced commanders. Dagno in northern Albania fell, while the Thopias were returned to their former state. After a strong counterattack by Arianiti, the Ottomans were soon defeated. This victory strengthened the revolt in southern Albania, especially in Kurvelesh. Murad II headed for Albania and chose to camp at Serez in Macedonia, from where he sent out a force of 10,000 into Albania under Ali Beg. The army of Ali Beg, in the winter of 1432–33, went through the tight valleys of the Shkumbin; near Buzurshekut (Bërzeshtës), the Albanians ambushed the Ottoman army. Arianiti observed and maneuvered against the Ottomans while also encouraging his men, eventually leading to an Ottoman rout. This victory further strengthened the Albanian cause and gave hope to the Europeans who feared a major Ottoman invasion. The Byzantine chronicler, Chalcondyles, wrote: ""In this battle, Arianit Komneni won a glorious victory."" With these victories Gjergj Arianiti expanded his domains up to the city of Manastir.
