The Sokol movement (ˈsokol, falcon) is an all-age gymnastics organization first founded in Prague in the Czech region 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". The 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. The movement also spread across all the regions populated by Slavic cultures, most of them part of either Austria-Hungary or the Russian Empire: present-day Slovakia, the Slovene Lands, Croatia, Serbia (SK Soko), Bulgaria, Poland (Sokół), Ukraine, Belarus. In many of these nations, the organization also served as an early precursor to the Scouting movements. Though officially an institution "above politics", the Sokol played an important part in the development of Czech nationalism and patriotism, which found expression in articles published in the Sokol journal, lectures held in the Sokol libraries, and theatrical performances at the gymnastic mass festivals called slets. The idea for physical training centers was not a new one. The Sokol movement consciously traced its roots in physical education to the athletes and warriors of Ancient Greece. More directly, the nature of the Sokol was influenced by the German Turnverein, mass-based, nationalist-minded gymnastics societies founded by Friedrich Ludwig Jahn in 1811. Miroslav Tyrš, the founder of the first Sokol in Prague in 1862, continued as the most influential figure in the movement until his death in 1884. Born Friedrich Emanuel Tirsch into a German-speaking family in 1834, Tyrš grew up under the influence of the Romantic nationalism that gave rise to the uprisings that swept across Europe in 1848. He received a thorough education at the University of Prague, where he majored in philosophy. It was not until the early 1860s that he became involved in the Czech nationalist cause, and changed his name to the Slavic form.
