Stellaland, officially known as the Republic of Stellaland (Dutch: Republiek Stellaland) from 1882–1883 and, after unification with the neighbouring State of Goshen, as the United States of Stellaland (Dutch: Verenigde Staten van Stellaland) from 1883–1885, was a Boer republic located in an area of Bechuanaland, west of the Transvaal.
The principle issue that dominated Upington's short Ministry was the conflict over two tiny Boer mercenary states – Stellaland and Goshen – which had been established by Boer invaders in "British" Bechuanaland and which the British demanded were ejected.
