J. B. M. Hertzog in the context of "National Party (South Africa)"

The Balfour Declaration of 1926 was issued by the 1926 Imperial Conference of British Empire leaders in London. It was named after Arthur Balfour, who was Lord President of the Council. It declared the United Kingdom and the Dominions to be:

The Inter-Imperial Relations Committee, chaired by Balfour, drew up the document preparatory to its unanimous approval by the imperial prime ministers on 15 November 1926. It was first proposed by South African Prime Minister J. B. M. Hertzog and Canadian Prime Minister William Lyon Mackenzie King.

The Women's Enfranchisement Act, 1930, was an act of the Parliament of South Africa which granted white women aged 21 and older the right to vote and to run for office. It hence diluted the voting power of non-white people in the Cape Province by effectively doubling the number of white voters. It was enacted by the National Party government of Prime Minister J. B. M. Hertzog.

The first general election at which women could vote was the election of 17 May 1933. At that election Leila Reitz (wife of Deneys Reitz) was elected as the first female MP, representing Parktown for the South African Party.

Imperial Conferences (Colonial Conferences before 1907) were periodic gatherings of government leaders from the self-governing colonies and dominions of the British Empire between 1887 and 1937, before the establishment of regular Meetings of Commonwealth Prime Ministers in 1944. They were held in 1887, 1894, 1897, 1902, 1907, 1911, 1921, 1923, 1926, 1930, 1932 and 1937.

All the conferences were held in London, the seat of the Empire, except for the 1894 and 1932 conferences which were held in Ottawa, the capital of the senior Dominion of the Crown. The 1907 conference changed the name of the meetings to Imperial Conferences and agreed that the meetings should henceforth be regular rather than taking place while overseas statesmen were visiting London for royal occasions (e.g. jubilees and coronations).

The Herenigde Nasionale Party (English: Reunited National Party; HNP) was an Afrikaner nationalist and conservative political party in South Africa. It was founded in 1940 from the merger of the Purified National Party (Gesuiwerde Nasionale Party, GNP) led by future prime minister D. F. Malan and a faction of the United Party (UP) led by J. B. M. Hertzog, who split from the party and resigned as prime minister of South Africa in opposition to the country's support for the Allies during World War II. The HNP won a plurality of seats at the 1948 general election despite losing the popular vote to the UP and formed a coalition government with the Afrikaner Party (AP), which it merged with to form the National Party (NP) in 1951; the NP name had previously been used by the party Hertzog merged into the UP.
