Nagykálló

Nagykálló was a market town of Szabolcs County on the road between Debrecen and Munkács. The Kállay family held the settlement, where county assemblies and courts met in the Middle Ages. A frontier fortress built around 1570 strengthened its importance during the Ottoman wars. In 1609 hajdu soldiers settled at Kálló were moved to Böszörmény after disputes with the imperial garrison, while Kálló continued to serve as a county centre.
