History of Nairobi plague and the subsequent burning down of the original town. By 1905, Nairobi was a humming commercial center and replaced Mombasa as capital of the British East Africa. The city expanded, supported by the growth in administrative functions and in tourism, initially in the form of British big game hunting. As the British colonialists explored the region, they began using Nairobi as their first stop. This prompted the colonial government to build several grand hotels in the city for British tourists and big game hunters. Nairobi continued to grow under British rule, and many Britons settled within the city's suburbs.
