Pankration

Pankration (; Greek: παγκράτιον) was a sporting event introduced into the Greek Olympic Games in 648 BC, which was an empty-hand submission sport with few rules. The athletes used boxing and wrestling techniques, but also others, such as kicking, holds, joint-locks, and chokes on the ground, making it similar to modern mixed martial arts.
The term comes from the Greek παγκράτιον [paŋkrátion], meaning ‘all of power’, from πᾶν (pan) ‘all’ and κράτος (kratos) ‘strength, might, power’.
