The Holocaust in Romania refers to the genocide of Jews carried out by Romanian state authorities, military, and allied paramilitary groups in the Kingdom of Romania and Romanian-occupied Soviet territories between 1940 and 1944. This genocide was largely independent of direct SS involvement, making Romania the only Axis ally to conduct such a campaign without Heinrich Himmler's intervention. Estimates of Jewish deaths range from 250,000 to 380,000, with an additional roughly 132,000 Jews killed in Hungarian-controlled Northern Transylvania by Nazi and Hungarian collaboration during the same period. Romania is described as ranking first among Holocaust perpetrator countries other than Germany.
The roots of this genocide are traced to rising antisemitism in Romanian political and cultural life during the early 20th century, promoted by figures such as A.C. Cuza, Nichifor Crainic, Nicolae Iorga, and organizations including the Iron Guard, founded from earlier nationalist movements associated with Corneliu Zelea Codreanu. Romania enacted antisemitic legislation in 1938 under Octavian Goga's government, stripping citizenship from over 225,000 Jews, making it the second European state to pass such laws after Nazi Germany and the first to do so before the Anschluss.
Violence escalated after Romania lost Bessarabia and Northern Bukovina to the Soviet Union in 1940, with military units killing Jews accused of collaboration, including the Dorohoi pogrom. In January 1941, the Bucharest pogrom under Iron Guard control killed 125 Jews and destroyed over 1,000 buildings. The Iași pogrom in June 1941 led to mass killings and deportation via "Death Trains," in which thousands died from suffocation, dehydration, and violence during transit, contributing to up to 14,850 total victims.
Following Romania's participation in the German invasion of the Soviet Union in June 1941, Romanian authorities implemented a policy termed "cleansing of the land" across Bessarabia, Bukovina, and later Transnistria. This included mass shootings coordinated with German Einsatzgruppe D, forced marches, ghettoization, and deportations to camps in Transnistria, where conditions caused widespread death from starvation, exposure, and disease. At the Bogdanovka camp, a typhus outbreak in December 1941 led to the mass killing of most of its roughly 54,000 inmates, including burning victims alive in stables.
Romania's actions have been characterized by historians as a genocide "operationally separate" from the Nazi Final Solution, and Romania declined to deport Romanian Jews to the Belzec concentration camp. A 19 August 1941 statement attributed to Adolf Hitler acknowledged that Ion Antonescu's regime was pursuing more radical anti-Jewish policies than Germany at that time.
