The Dutch Cape Colony in southern Africa becomes the British Cape Colony as a result of the Battle of Blaauwberg.

The Dutch Cape Colony, officially known as the Cape of Good Hope Waystation, was a colony of the Dutch East India Company (VOC) and Batavian Republic in Southern Africa. Centered on the Cape of Good Hope, from where it derived its name, it was founded in 1652 by a VOC expedition under Jan van Riebeeck to serve as a re-supply and layover port for VOC vessels trading with Asia. The Cape was under VOC rule from 1652 to 1795 and Batavian rule from 1803 to 1806. Much to the dismay of the VOC's shareholders, who focused primarily on making profits from the Asian trade, the Cape Colony rapidly expanded into a settler colony in the years after its founding.

The Cape Colony, also known as the Cape of Good Hope, was a British colony in present-day South Africa named after the Cape of Good Hope. It existed from 1795 to 1802, and again from 1806 to 1910, when it united with three other colonies to form the Union of South Africa, then became the Cape Province, which existed even after 1961, when South Africa had become a republic, albeit, temporarily outside the Commonwealth of Nations (1961–94).

The Battle of Blaauwberg was a successful British amphibious operation during the War of the Third Coalition which lasted from 8–18 January 1806 and resulted in the capture of the Dutch Cape Colony. After defeating their Batavian opponents, the British signed a treaty under the Treaty Tree in Woodstock, Cape Town which established Britain's control over the Cape Colony. The colony later became a permanent part of the British Empire following the Congress of Vienna that marked the end of the Napoleonic Wars in 1814. Due to establishing permanent British rule over the Cape Colony, the battle would have many ramifications for southern Africa during the nineteenth and twentieth centuries. A bi-centennial commemoration of the battle was held in January 2006.
