Even so, the Voivodeship of Transylvania "was the largest single administrative entity"[4] in the entire kingdom in the 15th century. Voivodes enjoyed income from the royal estates attached to their office, but the right to "grant lands, collect taxes and tolls, or coin money"[5] was reserved for the monarchs. Although Roland Borsa, Ladislaus Kán and some other voivodes rebelled against the sovereign, most remained faithful royal officials.
