Greater South Africa
During the late 19th century and early 20th century, a number of South African and British political leaders advocated for a Greater South Africa. This irredentism can be regarded as an early form of Pan-Africanism, promoting an ethnic state for White Africans in much the same way as later Pan-Africanism focused on an ethnic state for Black Africans.
Statesman Jan Smuts repeatedly had called for South African expansion since 1895, envisioning a future South African border along the river Zambesi or even the equator. German South-West Africa, Southern Rhodesia, and at least the southern parts of Portuguese Mozambique (especially the port of Lourenço Marques in the Delagoa Bay) along with the High Commission Territories (Basutoland, Bechuanaland and Swaziland, the last one having been a Transvaal protectorate from 1890–99) were to be included in this state, with Pretoria now being its geographical capital. Although the initial objective of Smuts' expansion plan was the Zambesi, he took great geopolitical interest in the East Africa Protectorate and Tanganyika: he was impressed with the British colonists of the White Highlands and believed that the area could be transformed into a "great European state or system of states" in the near future, eventually leading to a "chain of white states which will in the end become one from the Union to Kenya". Smuts believed this expansion would finally lead South Africa to become "one of the greatest future Dominions of the Empire", the equal of Australia and Canada.
Smuts' expansionist aims received little domestic white support. Afrikaner nationalists feared that the incorporation of British territories near South Africa would result in a state with a much larger black majority than in the then-current Union of South Africa.
The formation of the Union in 1909 was seen as the first step in bringing forth the unification of the British-held territories in Southern Africa. The British were initially supportive of territorial enlargement of the South African State. The retainment of imperial responsibility in the Rhodesias, Nyasaland and the High Commission Territories was not intended to be the ultimate territorial arrangement either by the British or the South Africans: the South Africa Act 1909 made provisions for admitting Rhodesia as a fifth province of the Union in the future, and laid out the terms for the potential future transfer of the High Commission Territories. Prime Minister Louis Botha agreed with Smuts that the South African annexation of the High Commission Territories was only a matter of time.
The British approved Smuts' war aims during the South-West Africa Campaign, and supported the mandation of German South-West Africa to South Africa, although Smuts looked to formally incorporating the territory. He suggested the naming of this new territory as Bothaland after the Prime Minister. Even future fulfillment of the territorial objects in Portuguese Mozambique – by the means of a purchase approved unanimously by the South African cabinet – were looked favorably, despite Portugal being a member of the Entente.
However, the Southern Rhodesian government referendum of 1922 saw the colony of Southern Rhodesia reject joining the Union. This decision made the South African acquisition of the British South African Company rights in Bechuanaland unnecessary, and thus its transfer to the Union was halted. Rhodesia, functioning as a British counterweight to Afrikaner dominance, had laid claims to at least a part of Bechuanaland, and thus it was increasingly in British interests to transfer the latter from the South African sphere of influence. The British were also disappointed with the South African parliament passing the Natives Land Act, which created the land tenure system which eventually became one of the foundations of Apartheid.
Without Rhodesia, Smuts' projections for further South African expansion northward became impossible to actualize and his aspirations towards Mozambique difficult to accomplish. The South African general election of 1924 brought the end of Smuts' premiership and the election of J. B. M. Hertzog as the new Prime Minister. The British were suspicious of the anti-imperial and pro-Afrikaner Hertzog compared to the anglophile Smuts, and became less willing to meet South African territorial demands.
In the Afrikaner dominated Apartheid South Africa, especially under the premiership of Hendrik Verwoerd, the concept of an incorporation of Southern African territories into a white dominated South Africa revived, aiming now at Botswana, Lesotho and Swaziland which became independent from the United Kingdom in this time.
