Glima is a type of Viking wrestling. It is the national sport of Iceland. It is called a "back-hold" form because a wrestler grips his opponent around the torso, waist, or chest and then clasps his hands at his opponent's back.
The wrestlers wear special clothing that lets them get a grip on their opponent. This clothing covers more of the body than the Sumo wrestler's diaper-like clothing.
The sport has standardized moves and a match ends with one fall. The object is to put the opponent on the floor, not to push him out of the ring. The sport became less popular after the arrival of Christian priests into Scandinavia. These priests regarded it as a pagan activity. The people of Iceland however thought it good for physical and moral development and continued to practice the sport.
