Staring from Scythians and sarmats, who whooped Goth’s and roman's backs,(Atilla and company ) through Rus Kyivienne (Київська Русь) with knyaz Svyatoslav the Conqueror who defeataed Khozars kaganat

( By the way, he had old warriors iroquese style haircut-чуб, оселедець) to Cossacks republic. All of this was happening on current Ukraine's territory. Great warriors, with great military traditions have place in Easter Europen history.Talking about cossacks. I think everyone knows about Ukrainian cossack dance-"hopak" with all incredible jumps, kicks and turns.

This was the way to keep training and movements alive under Tsar's regime, when all Ukrainian was prohibited. Same story continued in USSR times, when communists where trying to make all people same and all different nations to become russins.
Thanks God this evil empire collapsed and free countries started to rediscover they national heritage. There is a loot great books in Ukraine about Slavic fighting styles, there are great people in the history (Ivan Piddubnyi) Unfortunately they are not that hugely promoted in Western world. For example, why American's take Capoeira, or Philipino or Islamic martial art's seriously, but disrespect Ukrainian, Russian, or Bellorussian styles?
Just because we do not have this huge PR and advertising?
