The Sokol movement is an all-age gymnastics organization founded in Prague in the Czech lands of Austria-Hungary in 1862 by Miroslav Tyrš and Jindřich Fügner. It was based upon the principle of "a strong mind in a sound body". Sokol, through lectures, discussions, and group outings, provided what Tyrš viewed as physical, moral, and intellectual training for the nation. This training extended to men of all ages and classes, and eventually to women.
