Taras Bulba, a character made famous by comics was a Cossack warrior icon.
Cossacks are Slavic warrior peasants living on the Ukrainian steppe and famed for horsemanship. Self-governing under leaders like Bohdan Chmielnicki (c. 1595-1657), they resisted outside authority but served the tsars as irregular cavalry, pioneered in Siberia and fought the Bolsheviks 1918-21. Collectivisation broke up their communities in the 1930's, but cossack cavalry served in WWII.
