The Ossewabrandwag ("Oxwagon Sentinel") was a nationalist Afrikaner organization in South Africa, founded in Bloemfontein on February 4, 1939. It opposed South African entry into World War II on the British side, and created a paramilitary group called Stormjaers, modelled on the Nazi SA, which carried out sabotage against Jan Smuts' government. After the war the Ossewabrandwag went underground, but many of its members rose in the ranks of the Apartheid government.
