Another Arab scholar, Ibn Battuta, who passed through the region in 1330 and 1331, talks about Baba Saltuk (Babadag) as the southernmost town of the Tatars.

[6] 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 Danube Delta.

[7] After the Russian annexation of Crimea in 1783 Crimean Tatars began emigrating to the Ottoman coastal provinces of Dobruja (today divided between Romania and Bulgaria).

Once in Dobruja most settled in the areas surrounding Mecidiye, Babadag, Köstence, Tulça, Silistre, Beştepe, or Varna and went on to create villages named in honor of their abandoned homeland such as Şirin, Yayla, Akmecit, Yalta, Kefe or Beybucak.[when?]

They played a key role in Mahmud II's struggle with Mehmet Ali Pasha of Egypt, suppressed rebellions in Bosnia and Herzegovina, Kurdistan, and the Arab provinces and served with the Ottomans during the Crimean War.

[citation needed] Tatars together with Albanians served as gendarmes, who were held in high esteem by the Ottomans and received special tax privileges.

A Dobrujan Tatar, Kara Hussein, was responsible for the destruction of the Janissary corps on orders from Sultan Mahmut II.

[citation needed] From 1877-1878 it is estimated that between 80,000 and 100,000 Crimean Tatars emigrated from Dobruja to Anatolia, which continued in smaller numbers until World War I.

Other reasons included the 1899 famine in Dobruja, a series of laws from 1880 to 1885 regarding confiscation of Tatar and Turkish land, and the World War I (1916–18) which devastated the region.

[8] When Ismail Gasprinski, considered by many to be the father of Crimean Tatar nationalism, visited Köstence (Constanţa) in 1895 he discovered his newspaper Tercüman was already in wide circulation.

Most have emigrated to Turkey but it is estimated that a few thousand Nogais still live in Dobruja, notably in the town of Mihail Kogălniceanu (Karamurat) and villages of Lumina (Kocali), Valea Dacilor (Hendekkarakuyusu) and Cobadin (Kubadin).
