'British East Africa' was an area of East Africa controlled by the
British in the late 19th century, which became a
protectorate covering roughly the area of present-day
Kenya. It grew out of British commercial interests in the area in the 1880s and lasted until 1920, when it became the colony of Kenya.
European missionaries began settling in the area from
Mombasa to
Mount Kilimanjaro in the 1840s, nominally under the protection of the
Sultan of
Zanzibar. In 1886 the British government encouraged
William Mackinnon, who already had an agreement with the Sultan and whose shipping company traded extensively in East Africa, to establish British influence in the region. He formed a British East Africa Association which led to the
Imperial British East Africa Company being chartered in 1888. It administered about 150 miles of coastline stretching from from the river
Tana via Mombasa to
German East Africa which were leased from the Sultan. The British "sphere of influence", agreed at the
Berlin conference of 1885, extended up the coast and inland across the future Kenya, and after
1890 included
Uganda as well.
However, the company began to fail, and on
July 1,
1895 the British government proclaimed a protectorate, and in
1902 made the Uganda territory part of the protectorate also. The capital was shifted from Mombasa to
Nairobi in
1905, and on
July 23,
1920 the protectorate became the
Kenya Colony.
Stamps and postal history of British East Africa

Sun and crown, 1890

1895 overprint

2 1/2 annas, 1896
The early missionaries sent letters by runner to
forwarding agents at Zanzibar. Post offices opened at Mombasa and
Lamu in
1890, and after some initial surcharges of British
postage stamps with values of 1/2, 1, and 4
annas, the Company issued stamps using a symbolic sun and crown design and inscribed '"IMPERIAL BRITISH EAST AFRICA COMPANY"', all valued in annas and rupees.
Shortages between
1891 and 1895 resulted in a variety of surcharges on these, and the protectorate in 1895 was marked by overprints reading '"BRITISH / EAST / AFRICA"' and overprints of '"British / East / Africa"' on stamps of
India. The protectorate joined the
Universal Postal Union at this time.
In
1896 a series depicting
Queen Victoria was issued, inscribed '"BRITISH EAST AFRICA"', although these ran short in
1897 and stamps of Zanzibar were overprinted as the stamps of India had been previously. A number of post offices opened along the
Uganda Railway, which was started in
1896 at Mombasa and reached
Kisumu on
Lake Victoria in
1902.
In
1901 the postal administration was merged with that of Uganda, and in
1904 stamps issued for the combined
East Africa and Uganda Protectorates came into use.
