Yunak Gymnastic Society

Yunak (Bulgarian: Юнак) was a national network of sports societies in Bulgaria at the end of the 19th and the first half of the 20th centuries.

The word yunak means a strong, nearly invincible young man, and is sometimes translated as "hero" or "champion".

The Yunak society quickly grew and, at its peak in the early 1940s, it had a membership of nearly 60 000 with 242 branches nationwide.

Yunak was an entirely amateur association, and its teams rarely participated in organized sports – although it is credited for much of Bulgaria's Olympic talent at the time.

The society was made to enter a football team (which played in all-white) in the local championship after the communists came to power in 1944.
