The Croatian Air Force Legion, or HZL, was a unit of the Luftwaffe, composed entirely of volunteers drawn from the nazi puppet-state, the Independent State of Croatia. Many of them had previously served in the Royal Yugoslav Air Force in April 1941 during the Nazi Invasion of Yugoslavia.

Lorković–Vokić plot was a mid-1944 attempt initiated by Interior Minister Mladen Lorković and Armed Forces Minister Ante Vokić to form a coalition government with the Croatian Peasant Party (HSS), abandon the Axis powers and align the Independent State of Croatia with the Allies with the help of the Croatian Home Guard. The plot originated from the HSS, which was also involved in the negotiations with the Allies. The plot ended with mass arrests and the execution of the major plotters, including Lorković and Vokić.
