I realize that Cossacks should be a part of Ukraine/Russia history but they were just so different, independent and cowboy-like people that they deserve their own place, especially since they messed up with Poland, but Polish commonwealth as not always good to them
Cossacks[nb 1] are a group of predominantly East Slavic–speaking people who became known as members of democratic, self-governing, semi-military communities, predominantly located in Eastern and Southern Ukraine and in Southern Russia. They inhabited sparsely populated areas and islands in the lower Dnieper, Don, Terek and Ural river basins and played an important role in the historical and cultural development of both Ukraine and Russia...
The Zaporizhian Sich were a vassal people of Poland–Lithuania during feudal times. Under increasing pressure from the Polish–Lithuanian Commonwealth, in the mid-17th century the Sich declared an independent Cossack Hetmanate, initiated by a rebellion under Bohdan Khmelnytsky. Afterwards, the Treaty of Pereyaslav (1654) brought most of the Cossack state under Russian rule. The Sich with its lands became an autonomous region under the Russian-Polish protectorate
Admiral (Russian: Адмиралъ) is a 2008 biopic about Alexander Kolchak, a vice-admiral in the Imperial Russian Navy and leader of the anti-communist White Movement during the Russian Civil War. The film also depicts the love triangle between the Admiral, his wife, and the poet Anna Timiryova.
