Lawrence of Transylvania
Lawrence (; died 1265 or 1266) was a Hungarian distinguished nobleman and military leader, who served as voivode of Transylvania between 1242 and 1252. His origin is uncertain; Tudor Sălăgean assigned him to the kindred Aba, however, according to Pál Engel, he belonged to the Illyéd branch of the "gens" Kán. He had a son from his unidentified wife, Lawrence II, who served as master of the cupbearers (1272–1273; 1274) and ban of Severin (1279; 1291). Lawrence was first mentioned by contemporary records in the first regnal year (1235) of Béla IV of Hungary, when he functioned as  ispán ("comes") of Fejér County. In 1238, a charter in a connection with donation from Andrew II of Hungary, referred to him as "former" ("tunc temporis") ispán, which implies Lawrence maybe already held that office during the end of Andrew's reign. He served as ispán of Bihar County between 1236 and 1238. He was appointed master of the cupbearers and ispán for the stablemen (; ) in 1240. After the Mongol invasion (1241–1242), where voivode Pousa, son of Sólyom died, the consolidation of the province of Transylvania was the main task of Lawrence, who was appointed voivode by Béla IV and  held the office for 10 years from 1242. He also fought in the royal army in a war against Austria in 1246 and participated in the battle of the Leitha River, where Frederick the Quarrelsome killed. Besides his voivodeship, Lawrence also functioned as ispán of Valkó County from 1248 to 1252. During the throne fights in the 1260s, he supported junior king Stephen, who rebelled against his father's rule and governed Transylvania independently from Béla IV, holding the title of duke of Transylvania. Consequently, Lawrence served as master of the treasury for Stephen between 1263 and 1265. He was  appointed ban of Severin () in 1263, where Stephen also exercised the royal rights.
