On 31 May, 1910, the Union of South Africa was established, marking its independence from the United Kingdom.
This union unified four British colonies—Cape Colony, Natal Colony, Transvaal Colony, and Orange River Colony—into a single nation under the sovereignty of the British Crown.
The creation of the Union of South Africa followed years of negotiations and was formalised by the South Africa Act 1909 passed by the British Parliament.
This act laid the foundation for a self-governing dominion, allowing the newly formed nation to exercise greater control over its internal affairs while remaining part of the British Empire.
The establishment of the Union represented a significant step in the region's political evolution, setting the stage for the complex and often contentious history that would follow.
