Southern Dobruja
The Quadrilateral covers 7,412 square kilometers of north-eastern Bulgaria. This area contains the provinces of Dobrich and Silistra. A population of 358,000 people currently lives within these borders. The land forms a distinct part of the historical region known as Dobruja. It sits at the crossroads of Bulgarian and Romanian history.
Bulgaria lost control of this territory after its defeat in the Second Balkan War. The Treaty of Bucharest signed in 1913 ceded Southern Dobruja to Romania. This transfer occurred while the region was still an autonomous principality since 1878. Bulgaria had become an independent state by 1908 before losing the land. The annexation marked the end of over three decades of Bulgarian administration.
Romania demanded all landowners prove their property rights in 1914. Owners had to surrender one third of claimed land or pay its value. Many peasants received redistributed plots from these seized estates. Tens of thousands of settlers arrived from Macedonia including Aromanians and Megleno-Romanians. Romanians from Wallachia also moved into the newly available farmland. Theodore I. Geshkoff noted that these reforms appeared to have a nationalist purpose.
Southern Dobruja returned to Bulgaria on the 7th of September 1940 under the Treaty of Craiova. This agreement mandated a compulsory population exchange between the two nations. About 110,000 Romanians were forced to leave the region. Almost 95% of those leaving had settled there after 1913. Meanwhile 77,000 Bulgarians departed Northern Dobruja for their homeland. Only a few hundred Romanians and Aromanians remain in Southern Dobruja today.
Census data reveals dramatic changes in ethnic composition across more than a century. In 1910 Bulgarians made up 47.6% of the 282,007 inhabitants. Turks comprised 37.8% while Roma accounted for 4.3%. By 1930 Romanian settlers reached 20.5% of the total population. The 2001 census showed Bulgarians rose to 69.5% of residents. Turkish populations dropped to 21.6% by that same year. Modern figures from 2011 show Bulgarians at 68% and Turks at 25.75%.
