The British wanted local black Africans to work in Natal as workers. But the locals refused, and as a result, the British introduced the indenture system, resulting in a permanent Indian South African presence. On 18 January 1826, the Government of the French Indian Ocean island of Réunion laid down terms for the introduction of Indian labourers to the colony. Each man was required to appear before a magistrate and declare that he was going voluntarily. The contract was for five years with pay of ₹8 (12¢ US) per month and rations provided labourers had been transported from Pondicherry and Karaikal. The first attempt at importing Indian labour into Mauritius, in 1829, ended in failure, but by 1834, with abolition of slavery throughout most of the British Empire, transportation of Indian labour to the island gained pace. By 1838, 25,000 Indian labourers had been shipped to Mauritius.
