The Main Ustaša Headquarters (Croatian: Glavni ustaški stan - GUS) was the ruling body of the Ustaša party in the Independent State of Croatia, convened under the poglavnik, Ante Pavelić.
[2] The Main Ustaša Headquarters evolved from Croatian Emigrant Office (Croatian: Hrvatska emigrantska kancelarija) established by Pavelić in Milan, Italy and managed by Stanko Hranilović who also used alias Stanko Đurić and was one of the closest associates of Pavelić at that time.
[7] The Main Ustaša Headquarters consisted of poglavnik, Doglavničko vijeće, Pobočnički zbor and commissioners.
[8] It is assumed that before the World War II only Mile Budak was appointed as doglavnik (in 1934) and Marko Došen as president of the Doglavničko vijeće.
[10] In May 1941 Pavelić signed the law which defined Main Ustaša Headquarters as supreme body of Ustaše organization.
