From 1783 to 1853 tens of thousands of Crimean Tatars and Nogais emigrated to the Rusçuk region which subsequently became known as "Little Tartary". Following the Russian conquest of 1812, Nogais from Bucak also immigrated to Dobruja. Tatars who settled in Dobruja before the great exodus of 1860 were known as "Kabail". They formed the Kabail Tatar squadron in the "Nizam-ı Cedid" (New Order) army of sultan Selim III. 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.
