Treaty of Neuilly-sur-Seine
In 1941, Bulgaria allied itself with Germany to regain the area of Dobruja which it had lost several years earlier at the signing of the Treaty of Neuilly-sur-Seine in 1919 after the War. In early 1943, Nazi officials requested that Bulgaria deport its Jewish population to workcamps throughout Germany and Poland. Later that year, King Boris succumbed to the German demand for the extradition of 11,343 Jews from territories re-occupied by Bulgaria. When trains came to take 49,000 more Bulgarian Jews to the death camps, the Bulgarian people resisted the demands of the German government and refused to allow their Jewish neighbors to be sent to concentration camps in what was the single largest non-deportation of Jews during World War II.
