Northern Dobruja

Northern Dobruja (Dobrogea de Nord or simply Dobrogea; Северна Добруджа, Severna Dobrudzha) is the part of Dobruja within the borders of Romania. It lies between the lower Danube River and the Black Sea, bordered in the south by Southern Dobruja, which is a part of Bulgaria.

History
Around 600 BC, the Greeks colonized the Black Sea shore and founded numerous fortresses: Tomis (today's Constanța), Callatis, Histria, Argamum, Heracleea, Aegysus. The Greeks engaged in trade with the Dacians who lived on the main land. Dobruja became a Roman province after the conquest of the Dacian Tribes. One of the best preserved remnants of this period is the Capidava citadel.

Between the 7th and 14th century, Dobruja was part of the First Bulgarian Empire and the Second Bulgarian Empire.

For a long period in the 14-15th century, Dobruja became part of Wallachia. The territory fell under Ottoman rule from the mid-15th century until 1878, when it was awarded to Romania for its role in the 1877-78 Russo-Turkish War, and as compensation for the transfer of a region partly overlapping Southern Bessarabia. Under the treaties of San Stefano and Berlin, Romania received Northern Dobruja while the newly restored Principality of Bulgaria received the smaller southern part of the region. After the Second Balkan War in 1913, Romania also annexed the Bulgarian Southern Dobruja, which it ruled until the signing of the 1940 Treaty of Craiova. The treaty was approved by Britain, Vichy France, Germany, Italy, the Soviet Union and the United States. It included a population exchange which removed the Bulgarian minority from Northern Dobruja, which was evacuated to the southern part. At the same time, the Romanians (including Aromanians and Megleno-Romanians) from Southern Dobruja were brought north of the border. There also is a Csángó Hungarian village in Northern Dobruja, in the Constanța County, known as Oituz.

Geography
