Terms of the Treaty provide for the mandatory resettlement of Romanian citizens of Bulgarian ethnicity living in Northern Dobruja to Bulgaria, and the resettlement of ethnic Romanians living in Southern Dobruja to Romania. 110,000 Romanians (80,000 of them from South Dobruja) were forced to leave their homes in Southern Dobruja and other parts of Bulgaria. Most of these Romanians were colonists who had settled there after the Second Balkan War in 1913, when the territory was annexed by Romania (see Treaty of Bucharest (1913)). 65,000 Bulgarians left their homes in Northern Dobrudja and resettled in Bulgaria.
