Mombasa is a coastal city in southeast Kenya along the Indian Ocean. It is the country's oldest (circa 900 AD) and second-largest city, after the capital Nairobi.
In 1698, the town came under the influence of the Imamate of Oman, subordinate to the Omani rulers on the island of Unguja. On 24 June 1837, Mombasa was nominally annexed by Said bin Sultan of Muscat and Oman.
On 25 May 1887 Mombasa was relinquished to the British East Africa Association, later the Imperial British East Africa Company. It came under British administration in 1895. It soon became the capital of the British East Africa Protectorate.
