The Black Legion (Croatian: Crna Legija), officially the 1st Standing Active Brigade (Prvi stajaći djelatni sdrug), was an Ustaše Militia infantry unit active during World War II in Independent State of Croatia.

[1] The Black Legion was formed in Sarajevo in April 1941 with 12 founding members, of whom 11 were Croats and one was a Bosnian Muslim.

Under Stipković's command the Legion lost even more men when the 23rd and 28th battalions (composed mainly of Bosnian Muslims) were disbanded and their soldiers transferred to the 13th Waffen Mountain Division of the SS Handschar.

Near the end of 1944 the Legion was incorporated into the 1st division of the Croatian Armed Forces under the command of General Roman Domanik.

When the war ended, many soldiers of the Black Legion refused to surrender and joined the Crusaders.
