The article shows the complete process of the revival and development of the Catholic physical education organisation Orel (Eagle) after the First World War until its dissolution at the end of 1929. The organisation, which was founded in 1906 as an antithesis to the liberal organisation of Sokol but simultaneously on the basis of Sokol’s findings, continued down its unique successful path after the war. It finally became a self-managed organisation, adapted to the new Yugoslav situation, made international connections, elevated itself in the field of sport, and remained fundamentally true to its programme and purpose, i.e. raising physically and spiritually strong Catholic Slovenians who would be a source of support for the Catholic side.
