In 1894, Swaziland became a protectorate of the South African Republic, which was under British control after the Second Anglo Boer War. The Swazi people refused to sign the proclamation, but the two powers signed another convention that effectively gave the terms unilateral effect.

1881: The British government signed a convention recognizing Swazi independence.
1902: The British assumed control of Swaziland from South Africa.
1903–1906: Swaziland became a British High Commission Territory, along with Basutoland (now Lesotho) and Bechuanaland (now Botswana).
1921: King Sobhuza II succeeded to the throne.
1964: Swaziland's first constitution entered into force.
1967: A new constitution came into effect, providing for the introduction of self-government once independence is gained.
1968: Swaziland regained its full independence on September 6.
