Obrana národa

Obrana národa (ON) (English: Defence of the Nation) was a Czech resistance organization  that fought against the German occupation from 1939 to 1945. It opposed Nazi rule in the Protectorate of Bohemia and Moravia. The group was founded by General Josef Bílý in April 1939.

The Gestapo was able to seek out and destroy the group's leadership on three occasions (February 1940, May 1942 and June 1944), but each time the group was reorganized.
