The Repression of communists in the Kingdom of Romania was political repression against people who held communist views in the Kingdom of Romania between 1921 and 1944. In 1921, a number of 271 members of the Socialist-Communist Party who voted for the affiliation of the party into the Third International were arrested and the following year they were tried and convicted by a military court to various terms of forced labour.
The 1924 Mârzescu Law banned the Romanian Communist Party and provided the death penalty for communist agitators, forcing the party to go underground for the following decades. Members of the Communist Party were routinely arrested by the police and Siguranța, the secret police. During this period, most leaders of the Communist Party were either in exile in the Soviet Union (the Moscow wing) or in prison (known as the prison wing).
In May 1921, as the members of the Socialist-Communist Party voted on the inclusion of the party into the Third International, the authorities stormed the assembly hall and arrested 271 members of the party. They were held for eight months, during which they were held in very tough conditions, some of them being tortured. In 1922, they were joined with anarchist Max Goldstein in a trial by military court in which they faced the charges of crimes against the state security, terrorism, collaboration with the enemy and instigation to riot. A number of politicians and intellectuals, including historian Nicolae Iorga, Dem I. Dobrescu and Iuliu Maniu voiced their discontent over the lack of constitutional basis for the trial.
