Historical Trajectory
Phase I: Rise
After the collapse of Austria-Hungary in 1918 and a turbulent period of revolutions, including the short-lived Hungarian Soviet Republic, Admiral Miklós Horthy suppressed the communist government during the White Terror and was appointed Regent in 1920. Although nominally a monarchy, no king was crowned. The Treaty of Trianon had stripped Hungary of over 70% of its former territory, making revisionism the central driver of the new state's politics and foreign policy.
Phase II: Zenith
In the early 1920s Hungary's conservative establishment stabilized the economy and consolidated Horthy's authoritarian rule. Foreign policy sought closer ties with Fascist Italy and Nazi Germany. Through the First and Second Vienna Awards in 1938 and 1940, Hungary recovered parts of Czechoslovakia and Romania. After joining the Axis invasion of Yugoslavia in 1941, Hungary briefly approached its greatest post-Trianon territorial extent, recovering Hungarian-majority borderlands lost two decades earlier.
Phase III: Decline
Heavy military losses on the Eastern Front by 1943–1944 prompted Horthy to secretly negotiate with the Allies. Germany preempted any defection by occupying Hungary in March 1944 and deposing Horthy in October, installing the fascist Arrow Cross Party under Ferenc Szálasi. Soviet forces overran the country by early 1945. Under Soviet influence, the state was renamed Hungarian State, then the Second Hungarian Republic was proclaimed in 1946, soon superseded by the communist Hungarian People's Republic in 1949.
