Nairobi was founded in 1899 by the colonial authorities in British East Africa, as a rail depot on the Uganda Railway. The town quickly grew to replace Mombasa as the capital of Kenya in 1907. After independence in 1963, Nairobi became the capital of the Republic of Kenya. During Kenya's colonial period, the city became a centre for the colony's coffee, tea and sisal industry. The city lies in the south-central part of Kenya, at an elevation of 1,795 metres (5,889 ft).
According to the 2019 census, in the administrative area of Nairobi, 4,397,073 inhabitants lived within 696 km2 (269 sq mi).
Home to thousands of Kenyan businesses and over 100 major international companies and organizations, including the United Nations Environment Programme (UN Environment) and the United Nations Office at Nairobi (UNON), Nairobi is an established hub for business and culture.
