Papers of the Afrikaner Party. After the declaration of war in September 1939, Genl. Hertzog and his followers broke away from the United Party and founded the Volks Party. The Volks Party then split up and one section joined the National Party to form the Herenigde [Re-united] National Party while the other section became the Afrikaner Party under the leadership of N.C. Havenga. During the 1948 election the HNP and AP joined forces. In 1951 the two parties amalgamated and became the National Party.
