Sotho people
In the late 1830s, Boer trekkers from the Cape Colony showed up on the western borders of Basutoland and subsequently claimed land rights. The trekkers' pioneer in this area was Jan de Winnaar, who settled in the Matlakeng area in May–June 1838. As more farmers were moving into the area they tried to colonise the land between the two rivers, even north of the Caledon, claiming that it had been "abandoned" by the Sotho people.
