Reichsbund der Kinderreichen

Reichsbund der Kinderreichen (RDK or RdK), Reich's Union of Large Families or literally: Reich's League of those wealthy in children, was one of the most important pronatalist groups founded in Germany after World War I.

The German Large Family League was forcefully nazified after the Nazi takeover of power in 1933.

The RDK was renamed Reichsbund Deutsche Familie, Kampfbund für erbtüchtigen Kinderreichtum (literally German Family Reich's League, Struggle League for a Hereditarily Strong Offspring), in April 1940, in the first years of World War II.

The American Military Government issued a special law outlawing the Nazi party and all of its branches.
