Naturism arose in Germany from the "life reform movement", starting around 1890. Around 1900, many youth groups were formed and later the boy scouts were added. These youth groups went hiking and also took a nude bath.
In the 1920s, the nudist clubs in Germany emerged from the "life reform movement". These nudist clubs initially focused on physical education and later on nude sports and later on simply about bare leisure time in community and family.
The "fkk-jugend" sees its purpose today in sports-oriented youth work.
The "BjN" sees his ideals more in the original youth groups and scouts and integrates naturism into the activities.
