Junker candidates had to be aged between 25 and 30 years old, belong to either the Nazi Party, the Hitler Youth, the Sturmabteilung, or the Schutzstaffel, be physically completely healthy, and be pure-blooded with no hereditary defects.
These schools were supposed to turn out future Party elite leaders, trained in both technical subjects and Nazi ideology.
Ordensburgen were designed for students who had completed the Adolf Hitler Schools, undergone six months of compulsory labor-service training, two years in the army, and who had already chosen their profession.
Each student was supposed to attend all four institutions in sequence, finishing at the historic site of the Medieval Marienburg for training that included live-fire military exercises.
The fourth and final Ordensburg, planned for the site of the historic Marienburg Castle in West Prussia, was never built.
