U historiografiji komunističke Jugoslavije problematika djelovanja civilnih i vojnih vlasti Nezavisne Države Hrvatske (NDH) na području današnje Bosne i Hercegovine tijekom Drugog svjetskog rata bila je djelomično istražena jer se ta tema nije mogla slobodno znanstveno istraživati niti se o njoj moglo slobodno pisati. U spomenutom razdoblju naglasak je bio na istraživanju partizanskog pokreta, dok je drugim sudionicima rata davana znatno manja pozornost. Oni koji su o toj temi pisali, malu ili gotovo nikakvu pozornost pridavali su sagledavanju okolnosti u kojima su utemeljena i djelovala tijela civilne i vojne vlasti NDH u Bosni i Hercegovini pa tako i na području bihaćko cazinskog kraja. Historiografskih istraživanja o glavnim značajkama civilnih i vojnih tijela vlasti NDH u Velikoj župi Krbava i Psat sa sjedištem u Bihaću nema. U radu je, na temelju izvornog arhivskog gradiva, prikazan Ustroj i djelovanje civilnih i vojnih tijela vlasti NDH u Velikoj župi Krbava i Psat sa sjedištem u Bihaću u razdoblju 1941.–1942. godine. Naime, nakon što je utemeljena 16. lipnja 1941. na području župe ustrojena su tijela općinskih, kotarskih i župskih tijela vlasti NDH, dok se ustroj vojne vlasti ogledao kroz uspostavu i djelovanje domobranskih i ustaških postrojbi te oružništva.In the historiography of communist Yugoslavia, the issue of the activities of the civil and military authorities of the Independent State of Croatia in today’s Bosnia and Herzegovina during the Second World War was partially explored because this topic could not be freely researched or written about. In the mentioned period, the emphasis was on researching the partisan movement, while other participants in the war were given much less attention. Those who wrote on this topic paid little or almost no attention to the circumstances in which the civil and military authorities of the Independent State of Croatia in Bosnia and Herzegovina were established and operated, as well as in the Bihać-Cazin region. There is no historiographical research on the main features of the civilian and military authorities of the Independent State of Croatia in the Great Parish of Krbava and Psat with its seat in Bihać. Based on the original archival material, the paper presents the structure and activities of civilian and military authorities of the Independent State of Croatia in the Great Parish of Krbava and Psat with its seat in Bihać in the period 1941-1942. Namely, after it was founded on June 16th, 1941, the municipal, county and parish authorities of the Independent State of Croatia were established in the parish, while the organization of military power was reflected in the establishment and operation of Home Guard and Ustasha units, and the armed forces
