At the point of the outbreak of the Second World War, in 1939, there were approximately 750,000 individuals who were of the Jewish faith. Yet fewer than half survived the war, despite the fact the Germany did not occupy the country. Clearly, though, there was influence from the Nazi Germany regime.
Most of the Jewish were killed by fellow Romanians in Pograms and shootings, coupled with starvation, disease and cold in the ghetto’s, after being deported to Transnistra. Transnistra is now located in the Pridnestrovian Moldavian Republic, which occupies a thin strip of land between the River Dniester and the border with Ukraine. It is internationally recognised as part of Moldovia.
In addition, 6,000 Romanian Jews died of heat stroke in the summer of 1941 in deportations on the “death trains” following the last Pogrom.
