After the break-up of Yugoslavia and Croatia's declaration of independence in 1991, the Republic of Serbian Krajina (RSK) was proclaimed in parts of Croatia, including parts of the Croatia—Banovina and Kordun—encompassing areas east of Karlovac and south of Sisak, marking the start of the Croatian War of Independence. After the January 1992 ceasefire, a United Nations peacekeeping force was deployed to the area. The area remained outside control of the government of Croatia until August 1995, when it was recaptured in Operation Storm. The Croatian Army campaign ended following the surrender of the last operational corps of the RSK military in Viduševac, near Glina. After the war, a number of towns and municipalities in the region were designated Areas of Special State Concern.
