A militantly anticommunist authoritarian government composed of military officers entered Budapest on the heels of the Romanians. A "white terror" ensued that led to the imprisonment, torture, and execution without trial of communists, socialists, Jews, leftist intellectuals, sympathizers with the KarolyiÍÍÍÍ and Kun regimes, and others who threatened the traditional Hungarian political order that the officers sought to reestablish. Estimates placed the number of executions at approximately 5,000. In addition, about 75,000 people were jailed. In particular, the Hungarian right wing and the Romanian forces targeted Jews for retribution. Ultimately, the white terror forced nearly 100,000 people to leave the country, most of them socialists, intellectuals, and middle-class Jews.
