British control of the Cape began permanently in 1806 and introduced major political, legal, and economic change.

​

Under British administration, the Cape developed into a formal colonial government with expanding infrastructure, trade, and legal institutions based on British traditions.

 

The nineteenth century also saw major population movements and the creation of new political entities beyond the Cape.

 

In response to British policies, including the abolition of slavery and changing land arrangements, many Dutch-speaking settlers migrated north and east in what became known as the Great Trek. These movements led to the establishment of independent Boer republics, notably the Orange Free State and the South African Republic (Transvaal).

 

British imperial expansion increasingly brought these republics into conflict with the British Empire.

 

This resulted in two Anglo-Boer Wars (1880–1881 and 1899–1902), the second of which ended in British victory and the incorporation of the Boer territories into the imperial system.

 

These events reshaped political power across southern Africa and accelerated the formation of a unified state.

 

Within the Cape, the period also saw -

​

•    growth in trade and port activity;

•    development of limited representative institutions; and

•    continued social and economic inequality.

 

By the early twentieth century, the Cape and former Boer republics were drawn together into a single political structure.
