When the Union of South Africa was formed in 1910, the electoral qualifications in use in each pre-existing colony were kept in place. In the Transvaal Colony, and its predecessor the South African Republic, the vote was restricted to white men, and as such, elections in the Transvaal Province were held on a whites-only franchise from the beginning. The franchise was also restricted by property and education qualifications until the 1933 general election, following the passage of the Women's Enfranchisement Act, 1930 and the Franchise Laws Amendment Act, 1931. From then on, the franchise was given to all white citizens aged 21 or over. Non-whites remained disenfranchised until the end of apartheid and the introduction of universal suffrage in 1994.
History
Losberg, like most of the Transvaal, was a conservative seat throughout its existence. For much of its history, it was a bellwether, being held by the governing party (or one of the governing parties) in every election from 1910 until 1981. It was notably represented early in its history by Louis Botha, who was Prime Minister between 1910 and 1919. In 1987, it was won by the Conservative Party, who held it in 1989.
