On September 19, 1698, people of Slabinja got a land charter (). They were granted land as a reward for the service in the Great Turkish War and a defense of the Croatian Military Frontier. The Charter guaranteed them a legal, undisturbed and protected land management in Slabinja. Also, with this act Count Péter Keglevich, Commander-in-chief of the Kostajnica confirmed their earlier taxation and tenancy rights. At the time, Knyaz Pavle Dragošević was administrating the County. He was appointed on March 1, 1693. The area was known as the Slabinja County () at the time. The County had three stockades (Upper, Middle, and Lower) and about a hundred people capable of military service according to the census on December 13, 1969.
