Like the German youth movement which emerged at the end of the nineteenth century, the Jewish youth movement comprised numerous associations with a romantic, back-to-nature focus. The Wandervogel was one of the most popular of the romantic, back-to-nature German youth movements. As they became more exclusionary and focused on an ethno-nationalist German identity, Jewish groups such as Blau-Weiss, Bund für jüdisches Jugendwandern in Deutschland were formed that would come to play a significant role in Jewish education, community organization, and Zionism. This 1919 photograph shows male and female members of a Jewish hiking and sports club on an outing to Medieval Grodziec castle in Lower Silesia.
