The convention was signed on 17 January 1852, by Commandant-General Andries Pretorius and others, on behalf of the new country, and Major William Samuel Hogge and Charles Mostyn Owen, clerk to the Civil Commissioner of Winburg, duly authorised to, and on behalf of, the British government. The treaty was signed on the farm called Sand River belonging to P. A. Venter, near Ventersburg.
Provisions
The treaty contained the following provisions:
The British government guarantees and grants the emigrant farmers across the Vaal river the right to govern themselves, according to their own laws free from any and all British interference and that the British Government wishes to promote peace, free trade and friendly intercourse with the new country
Britain disclaims any and all alliances with coloured nations to the North of the Vaal river
No slavery be practised in the country to the North of the Vaal river
Criminals will be exchanged between the British and the new country and that summonses for witnesses from both sides of the river be backed up by the magistrates at both sides of the river
It is agreed that certificates of marriages will be recognised on both sides of the river
It is agreed that any and all people now residing in British land but being in possession of land in the new country shall have the free right to sell the property and to move freely over the Vaal river.
Claims of contraventions
South African Republic authorities claimed the British contravened the treaty in 1853, with an English citizen, the missionary Livingstone supplying, storing and causing repairs to materials of war to the native tribes. Commandant Scholtz and his men confiscated a large number of rifles and amounts of ammunition and equipment from the home of David Livingstone. The British in turn claimed that the Boers were keeping slaves under the Inboekstelsel system. The Boers responded that the acts of a few criminals and criminal gangs cannot be claimed to be that of an entire nation.
One of the causes of the First Boer War was the direct breach by the British of this convention on 12 April 1877. Britain issued a proclamation called: "Annexation of the S.A. Republic to the British Empire," and proceeded to occupy Pretoria. Although the British did not attempt to dismantle the country, and self-rule was decreed in the proclamation, the annexation was not accepted by the South African Republic, and a delegation was sent to Europe and the United States to protest this action.
