Luangwa River
The other boundaries of the Central Africa Protectorate were also agreed around this time. The northern border was fixed at the Songwe River as part of an Anglo-German Convention in 1890. Its western border with Northern Rhodesia was fixed in 1891 at the drainage divide between Lake Malawi and the Luangwa River by agreement with the British South Africa Company, which governed what is today Zambia under Royal Charter until 1924.
