Johnston, Sir Harry (1858-1927), was a British explorer who played an important part in the foundation of British rule in east-central Africa. From 1879 to 1906, he explored many parts of Africa, including what is now Angola, the basin of the Congo River, and the area around Mount Kilimanjaro.
Johnston was British consul in Portuguese East Africa (now Mozambique) in 1889. He helped the British Empire acquire Northern Rhodesia (now Zambia) and Nyasaland (now Malawi). He was commissioner for British Central Africa from 1891 to 1896. Later, he became consul general in Tunisia and special commissioner in Uganda.
Johnston was born in London and named Harry Hamilton Johnston. He studied at King’s College, London, and the Royal Academy Schools.
