Basutoland placed under British protection

By early 1868, Orange Free State commandos had occupied most Basotho lowland territory after a decade of disputed boundaries, cattle raids, failed treaties and three wars. The Free State regarded its campaign as enforcement of recognised borders and peace terms; Moshoeshoe argued that those settlements had stripped his kingdom of essential land and repeatedly sought British intervention.

On 12 March 1868, the British government proclaimed Moshoeshoe and his people British subjects and their remaining territory under royal protection. The decision halted further Free State conquest and prevented the capture of Thaba Bosiu. It also extended British imperial authority rather than restoring full Basotho independence.

The Convention of Aliwal North in 1869 subsequently fixed a boundary that left the Free State with much of the conquered territory. The protected kingdom survived within reduced borders and later became the separate territory of Basutoland.

Significance

British protection preserved an identifiable Basotho state at a moment when its military position had become desperate. It simultaneously ended Free State expansion, recognised much of the Free State's territorial settlement and subordinated Basotho external sovereignty to Britain.
