Treaty of Craiova
The Treaty of Craiova (Bulgarian: Крайовска спогодба, romanized: Krayovska spogodba; Romanian: Tratatul de la Craiova) was signed on 7 September 1940 and ratified on 13 September 1940 by the Kingdom of Bulgaria and the Kingdom of Romania. Under its terms, Romania had to allow Bulgaria to retake Southern Dobruja, which Romania had gained after the 1913 Second Balkan War. Bulgaria had to pay 1 million lei as compensation for the investment provided to the region by Romania.
The treaty stipulated that a population exchange between Bulgaria and Romania had to be made. Thus, 103,711 Romanians, Aromanians and Megleno-Romanians living in Southern Dobruja were forced to move to Northern Dobruja (part of Romania), and 62,278 Bulgarians located in the north were forcibly moved to the south. The Dobrujan Germans, who were affected by these relocations, would eventually be transferred to Nazi Germany.
Unlike all other territorial treaties mediated by Nazi Germany, the Treaty of Craiova was not reversed by the Allies after WWII and Southern Dobruja remained Bulgarian.
