Abaúj County
During the reign of the last kings of the Árpád dynasty (late 13th century) Abaúj was de facto ruled by the Aba (family) (Slovak:Omodejovci).In the 16th-17th century many important historical events took place at least partly in Abaúj county, including the peasant revolt led by György Dózsa (1514), and battles between the Hungarians and the Ottomans.On 5 September 1619, the prince of Transylvania, Gabriel Bethlen captured Košice in Abauj with the assistance of the future George I Rákóczi in another anti-Habsburg insurrection.By the Peace of Nikolsburg in 1621, the Habsburgs restored the religious toleration agreement of 1606 and recognized Transylvanian rule over the seven Partium countries: Ugocsa, Bereg, Zemplen, Borsod, Szabolcs, Szatmar and Abauj.In 1918 (confirmed by the Treaty of Trianon 1920), the northern half of the Abaúj-Torna county (1551 km², including Kassa/Košice) became part of newly formed Czechoslovakia and continued to exist as an administrative unit till October 26, 1922, under the name Abovskoturnianska župa.After World War II, on January 20, 1945, the pre-war border was restored, with 52% of the original territory remaining in Hungary under the name of Abaúj county, with Szikszó as capital.
