Under the Treaty of Trianon (1920), Hungary was forbidden from owning military aircraft. However, a secret air arm was gradually established under the cover of civilian flying clubs. During 1938, as a result of the Bled agreement, the existence of the Royal Hungarian Air Force (Hungarian: Magyar Királyi Honvéd Légierő (MKHL) lit. "Royal Hungarian Home Guard Air Force"), was made known. The army's aviation service was reorganized and expanded.
Late 1938 the army aviation was once again reorganized. Admiral Horthy, the head of state, ordered that the army aviation should become an independent service effective 9 January 1939. Colonel Ferenc Feketehalmi Czeydner became the Air Section Chief in the Honvéd Ministry; Major General Waldemar Kenese became Inspector of the Air Force; Colonel Ferenc Szentnémedy became Chief-of-Staff, and Colonel László Háry was appointed head of the Magyar Királyi Honvéd Légierő (MKHL).
It subsequently participated in clashes with the newly established Slovak Republic and in the border confrontation with the Kingdom of Romania. In April 1941, operations were conducted in support of the German invasion of Yugoslavia and, on 27 June 1941, Hungary declared war on the Soviet Union.
In 1940, the decision was made to unite the Air Force, the anti-aircraft forces, and the civilian air defense organizations under one central headquarters.[citation needed] Colonel László Háry was retired 24 December 1940, and on 1 March 1941 the new organization was constituted. General András Littay became Air Sub-Department Chief, and Colonel Géza Vörös was appointed Head of the Air General Staff. On 1 June 1941, the Air Defense Corps was established, and Lieutenant General Béla Rákosi  became Commander of Army Aviation. In effect the Air Force had once again become part of the Army.
In the summer of 1942, an air brigade was attached to the Luftwaffe's VIII. Fliegerkorps on the Eastern Front. Beginning March 1944, Allied bomber raids began on Hungary and progressively increased in intensity. The 101st "Puma" fighter group (later wing) was the elite unit of the MKHL (its name and insignia are carried on by the "Puma" fighter squadron of the Hungarian Air Force of today). Late in 1944 all efforts were redirected towards countering the advancing Red Army, but to no avail. All fighting in Hungary ended on 16 April 1945.
