Crimean Tatars in Romania

Tatars (Romanian: Tătari), a Turkic-speaking ethnic group, have been present on the territory of today's Romania since the 13th century. According to the 2011 census, 20,282 people declared their nationality as Tatar, most of them being Crimean Tatars living in Constanţa County. They are the main factor of Islam in Romania.

The roots of the Crimean Tatar community in Romania began with the Cuman migration in the 10th century. Even before the Cumans arrived, other Turkic people like the Huns and the Bulgars settled in this region. The Tatars first reached the mouths of the Danube in the mid-13th century at the height of the power of the Golden Horde. In 1241, under the leadership of Kadan, the Tatars crossed the Danube, conquering and devastating the region. The region was probably not under the direct rule of the Horde, but rather, a vassal of the Bakhchisaray Khan. It is known from Arab sources that at the end of the 13th century and the beginning of the 14th century that descendants of the Nogai Horde settled in Isaccea. Another Arab scholar, Ibn Battuta, who passed through the region in 1330–31, talks about Baba Saltuk (Babadag) as the southernmost town of the Tatars.

The Golden Horde began to lose its influence after the wars of 1352-1359 and at the time, a Tatar warlord, Demetrius is noted defending the cities of the Mouths of the Danube. In the 14th and 15th centuries the Ottoman Empire colonized Dobruja with Nogais from Bucak. Between 1593 and 1595 Tatars from Nogai and Bucak were also settled to Dobruja. (Frederick de Jong)
