in 1437—38, while sanjakbey of the sanjak of albania was theodor's son yakup bey, theodor korona muzaka revolted in the region of berat. this revolt was, like previous albanian revolt of 1431–36, suppressed by the ottomans. even though in the albanian revolt of 1432–36 gjergj arianiti was victorious over ottomans and secured the independence and enlargement of his principality by including today's bitola. there are claims that muzaka's 1437—38 revolt is not supported by contemporary sources. jakub bey was recorded to be on the position of the sanjakbey of the sanjak of albania in 1442.
