The BSP were the third group in South Africa to openly advocate the restoration of the South African Republic and the Orange Free State and call for the secession of these territories from the Union of South Africa. Other groups advocated this notion in the past, with the Maritz Rebellion of 1914 and the Ossewa Brandwag of the 1940s being the most notable . This policy was later taken on board by the AWB and other rightist movements.
