During the Austro-Hungarian rule in Bosnia and Herzegovina, the present-day territory of Bosnia and Herzegovina was divided into counties ([[okrug]]) and kotars (districts). The territory of the Municipality of Bosansko Grahovo belonged to the Travnik Okrug and to the Kotar of Livno.

From 1929, the country was divided into banovinas (banates). The territory of the Municipality of Bosansko Grahovo became a srez on its own and belonged to the Vrbas Banovina.
During World War II, from 1941 to 1945, the municipality was a part of the Axis puppet state the Independent State of Croatia (NDH). Administratively, it belonged to the Grand Parish of Krbava and Psat, established on 16 June 1941. The seat of the Parish was in Bihać.
