The largest city in the region, Oradea (), was most probably established during the early years of Hungarian rule. It is first mentioned in 1113 under the name "Varadinum" in a diploma belonging to Benedictine Zobor Abbey. The Romanian name "Oradea" originates from the Hungarian name "Várad", meaning "fortified place". The city was one of the most important cultural centres of the medieval Hungarian state: two Hungarian kings, Ladislaus I (1077-1095) and Sigismund (1387-1437) were buried there. After the canonization of Ladislaus I in 1192, his shrine at Várad became a Catholic pilgrimage site.
