Leo von Caprivi arranged for the Caprivi strip to be annexed to German South West Africa in order to give Germany access to the Zambezi River as part of the Heligoland-Zanzibar Treaty. The German motivation behind the swap was to acquire a strip of land linking German South West Africa with the Zambezi River, providing easy access to Tanganyika (Tanzania) and an outlet to the Indian Ocean.
