The state of Goshen arose from a war in Bechuanaland in 1881–82.
It was established by a group of mercenaries who had fought in the war.
Goshen's independence was short-lived, though, as it was occupied by British forces in March 1885, and was later incorporated into British Bechuanaland.
The flag was evidently modelled on the 'vierkleur' Flag of the South African Republic, as well as the tricolor of either the German Empire or Upingtonia.
The official description was : Green against the hoist, and across from it black, white and red below each other.
