Ssireum, or Korean wrestling is the national sport of South Korea, which claims to be descended from ancient combat techniques and ritual sports performed in tribal states thousands of years ago. It is attested that the origin of the word Ssireum is Ssirunda, which means to struggle against each other, in the way horned animals such as oxen may compete for power.
Ssireum is played with both wrestlers grasping the waist band, called Satba, and trying to takedown the opponent. Even a single knee touching the ground is enough to lose. In the style, strength plays great importance, as well as technical intricacy to use the opponents momentum against them. There were originally two styles, left sided and right sided, practiced in southern parts and northern parts respectively. In 1994, the left sided style was made the standard style.
