Sloboda Ukraine
The town appeared in 1640 as a fort of the "Belgorod Defense Line" which Russian forces erected in Sloboda Ukraine to secure state southern borders from raids of Crimean Tatars and Nogais. Eventually the town developed into a district center of the Sumy Regiment which also served as a regional subdivision of the Sloboda Ukraine. After disbanding the regimental administrative division in 1765, Krasnopillya became a sloboda and a seat of volost (a county subdivision).
