AB meaning in Associations & Organizations ?

The Afrikaner Broederbond (AB) or simply the Broederbond was a secret, exclusively Afrikaner Calvinist male organisation in South Africa dedicated to the advancement of Afrikaner interests. It was founded by H. J. Klopper, H. W. van der Merwe, D. H. C. du Plessis and Rev. Jozua Naudé in 1918 and was known as Jong Zuid Afrika in Afrikaans (Young South Africa) until 1920, when it became the Broederbond. Its large influence within South African political and social life came to a climax with the rise of apartheid, which was largely designed and implemented by Broederbond members. Between 1948 and 1994, many prominent figures of South African political life, including all leaders of the government, were members of the Afrikaner Broederbond.
