What was one of the primary reasons for the annexation of the South African republics during the Second Boer War?

The annexation of the South African republics during the Second Boer War was primarily driven by the desire for gold and diamonds. The discovery of these precious resources in the late 19th century, particularly in the Witwatersrand area, sparked immense economic interest and competition. Britain aimed to consolidate control over these territories to secure access to the wealth generated by gold and diamonds. This economic motivation fueled tensions between the British colonial government and the Boer republics, ultimately leading to the war. Securing these resources was seen as critical for Britain's global economic ambitions and for enhancing its industrial capabilities.
