During the
Great Trek the
Boers moved out of the
Cape Colony seeking autonomy from British control. However, the expanding interests of the British colonial government soon caught up with the Boers when they annexed
Natal in 1845. After settling across the
Orange River, relations between the Boers and different groups between the Orange River and the
Caledon River were extremely strained; particularly between the Boers and the
Basotho.
Sir Harry Smith, the governor of the British Cape Colony at the time, decided to annex the area and set out clear boundaries. The land between the
Vaal River and the Orange River was annexed on 3 February 1848 and was officially proclaimed as the
Orange River Sovereignty. The Basotho lost a vast amount of land due to this annexation and the Boers were enraged by this process. Major
Henry Douglas Warden was subsequently forced out of
Bloemfontein in June 1848 by a Boer group led by
Andries Pretorius. In August 1848, Sir Harry Smith arrived with his army and fought the Boers in the
Battle of Boomplaats. The British came out victorious and one of the boundary lines created after this battle was called the Warden line. This line divided territory between the British and the Basotho and stretched from Cornetspruit and the Orange River through Vechtkop to Jammerbergdrift on the Caledon River. This action led to a conflict between the two groups where
Moshoeshoe I defeated the British in a battle known as Battle of Viervoet in 1851. The British government retracted their decision for annexation, claiming it was too expensive and difficult to maintain. In addition, the Boers wanted independence and threatened to side with Moshoeshoe I in a war against the British. The Boers were asked to send a delegation to a meeting with the British special commissioner Sir George Clerk in August 1853. This meeting was aimed at establishing some form of self-governance in the Orange River Sovereignty. When they could not agree, the Boers sent two members of their original delegation to Britain to try to convince the government to alter their decision. ==Convention==
