The Danube Cossack Host (Ukrainian: Дунайсько козацьке військо) was a Ukrainian Cossack Host formed in 1828 prior to the Russo-Turkish War (1828–1829), on the order of Emperor Nicholas I from descendants of the Zaporozhian Cossacks living in Bessarabia and in particularly the Budjak. Ukrainian Cossack Host named Lower-Danube Budjak Host had been formed there in 1807 but was disbanded soon afterwards. The Host also included some volunteers from the Nekrasov Cossacks and the Balkan peoples such as Romanians, Serbs and Bulgarians. Initially three selos of the Akkerman poviat were in the Cossacks control: Akmangit, Starokazachye, and Volonterovka.
