Sambo is a Russian martial art and combat sport. The word "SAMBO" is an acronym for SAMooborona Bez Oruzhiya, which literally translates as "self-defense without weapons". Sambo is relatively modern since its development began in the early 1920s by the Soviet Red Army to improve their hand-to-hand combat abilities.
The fighting style Sambo, originally conceived as a means of unarmed crowd control for the police, is a form of wrestling developed by the Soviets in the early 1930's. Sambo is a distillation of over 20 folk arts native to the Soviet Union as well as Greco-Roman Wrestling, Judo, Jujutsu, and free-style wrestling.
