Cossack man - who is it?

[ariel]

Shamil was never a “prince”, and emphatically not a “ cossack”
He was a leader of nationalistic/religious movement/war against Russian forces trying to subjugate the Caucasus. Under his leadership Islamic Caucasian nations fought Russian army ( including Cossacks).
His name is a Koranic Arabic modification of the Biblical prophet Samuel, in Hebrew: Shmuel, “ Hear G-d”.

If you are interested in the history of that 100-yeas-long war that never ended till today , get a book by Leslie Blanch “ The sabres of paradise”. Historically accurate, comprehensive and reads like Tom Clancy.
