Кубанские казаки
Most cultural productions in Kuban spanning 1890–1910, such as plays, stories, etc., were written and performed in the Ukrainian language, and one of the first political parties in Kuban was the Ukrainian Revolutionary Party. During World War I, Austrian officials received reports from a Ukrainian organization of the Russian Empire that 700 Kuban Cossacks in eastern Galicia had been arrested by their Russian officers for refusing to fight against Ukrainians in the Austrian army. Briefly during the Russian Civil War, the Kuban Cossack Rada declared Ukrainian to be the official language of the Kuban Cossacks, before its suppression by the Russian White leader General Denikin. .
