Abaúj (, , or ) is a historic administrative county (comitatus) of the Kingdom of Hungary. In parts of the 19th century, and in the beginning of the 20th century, it was united with Torna County to form Abaúj-Torna (Slovak: Abov-Turňa) county. Its territory is now in eastern Slovakia and north-eastern Hungary. Today Abaúj and Abov are only informal designations of the corresponding territories in Hungary and Slovakia. Geography Abaúj was situated some 20 km on both sides along the Hornád (Hungarian: Hernád) river between (including) Košice and (excluding) Miskolc. Abaúj shared borders with the Comitatus Scepusiensis (Hungarian: Szepes, German: Zips, Slovak: Spiš), Comitatus Sarossiensis (Hungarian: Sáros, Slovak: Šariš), Comitatus Zempliniensis (Hungarian: Zemplén, Slovak: Zemplín), Comitatus Borsodiensis (Hun: Borsod) and Comitatus Tornensis (Hungarian: Torna, Slovak: Turňa). Capitals Initially, the capital of the county was Forró. From the late 16th century the capital was Gönc, and Cassovia (Hungarian: Kassa, Slovak: Košice) has been the center of the county since the late 14th century. History According to Anonymus, during the reign of St. Stephen the Aba family (the family of Sámuel Aba who later became king) had properties in this area. The county arose in the second half of the 13th century from the comitatus Novi Castri (named after Novum Castrum, "new castle" – the castle itself stood in the center of the present-day village Abaújvár), which also included the later counties Šariš (Hungarian: Sáros) and Heves. During the Mongol invasion of Hungary a large part of the county was destroyed, but the castle of Abaújvár wasn't occupied by the invaders. After the invasion King Béla IV repopulated the area with German settlers. 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). Certain parts of the county was taken away from them after the Battle of Rozgony (June 15, 1312) by King Charles Robert. In a tax register from 1427 the county is mentioned as having 5187 peasant houses; 3500 in 1494-95. Before the battle of Mohács – marking the beginning of a 160-year-long Ottoman occupation of Hungary – the county had 9 castles, 14 towns, 318 villages and was owned by 275 landlords. 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.
