Cossack sword dancing started out as a pantomime of fights in battles. It has evolved into showing off as you dance around while twirling swords. Above is a collection of various people doing a sword dance. I wonder what an American helicopter mom would think of their tyke swinging swords around like the lad in the video.
Below is a video by Evgeny Kolot, a Cossack martial arts instructor demonstrating a sword dance in slow motion. It is nicely filmed and rather hypnotic. There are other good videos on his channel.
