Nairobi is the largest city and capital of Kenya. Founded in 1899 as a rail depot for the Uganda Railway, it rapidly grew into a commercial and administrative hub linking the East African Protectorate and later the Colony and Protectorate of Kenya with regional and global markets. The city is a focal point for regional diplomacy, hosting institutions such as the United Nations Environment Programme and the United Nations Office at Nairobi, and serves as headquarters for multinational firms and nongovernmental organizations.

History

The area that became Nairobi lay within the traditional territories of the Maasai and Kikuyu peoples, who engaged in pastoralism and agriculture before colonial contact. The decision by the Imperial British East Africa Company to construct the Uganda Railway in the late 19th century established a rail depot that evolved into a boomtown, driven by workers from British India, Somalia, Uganda, and Tanzania. Nairobi was designated the capital of the East African Protectorate in 1907, replacing Mombasa, and later became the capital of the Colony and Protectorate of Kenya.

During the interwar and postwar periods Nairobi expanded as a locus for colonial administration, settler agriculture, and commercial activity; landmarks such as the Kenya Railway headquarters building and the State House reflect that era. The city was central to political movements including the Mau Mau Uprising against colonial rule in the 1950s, and it played a role in negotiations leading to the Lancaster House Conferences and Kenyan independence in 1963. Post-independence Nairobi continued to attract investment, humanitarian agencies, and diplomatic missions, becoming a regional center for finance, culture, and multilateral engagement.

Geography and climate

Situated on the Nairobi River basin at an elevation of about 1,795 metres, the city lies just south of the Equator within the Guinea–Congo ecological transition zone. Its location on the high Kenyan Highlands moderates temperatures relative to lowland equatorial areas, producing a subtropical highland climate classified under the Köppen climate classification system as Cwb. Rainfall is bimodal, influenced by the Intertropical Convergence Zone; long rains occur from March to May and short rains from October to December. The urban footprint encompasses rolling hills, escarpments, and riparian corridors such as the Ngong River and tributaries that connect to surrounding national parks.

Demographics

Nairobi hosts a diverse population drawn from numerous ethnic groups including the Kikuyu, Luo, Luhya, Kalenjin, and Kamba, as well as sizable communities of Asian people, Arab people, and residents from Ethiopia, Somalia, and Sudan. Population growth accelerated in the late 20th century due to rural-to-urban migration and natural increase, challenging services and housing. Religious life is pluralistic, with adherents of Roman Catholic Church, Anglican Communion, Islam, Pentecostalism, and indigenous belief systems. The city’s demographic profile is youthful, contributing to dynamic informal economies, creative industries, and civic activism represented by groups such as Kenya Human Rights Commission and networks of community-based organizations.

Economy and infrastructure

Nairobi is a regional financial center hosting the Nairobi Securities Exchange, the Central Bank of Kenya, and headquarters for multinational corporations such as Safaricom and regional offices of UNICEF and World Bank. Key sectors include finance, information technology, tourism, and logistics; the city’s technology cluster around Waiyaki Way and the iHub innovation space has fostered startups and incubators. Industrial zones in areas like Industrial Area, Nairobi and logistics corridors linked to Jomo Kenyatta International Airport support manufacturing and export. Infrastructure challenges include water provision, sanitation, waste management, and power reliability; investments have involved partnerships with institutions such as the African Development Bank and bilateral donors.

Government and administration

The city is administered as a county under the devolved system established by the Constitution of Kenya 2010, with an elected governor and county assembly responsible for municipal services, land use, and development planning. Key national institutions located in the city include Parliament of Kenya and the Supreme Court of Kenya, which interact with county authorities on policy and legal matters. Security coordination involves national agencies such as the Kenya Defence Forces and Kenya Police Service alongside county-level emergency services. Urban governance has been shaped by initiatives like the Vision 2030 national development strategy and partnerships with international agencies for urban upgrading.

Culture and landmarks

Nairobi’s cultural life blends traditional and contemporary expressions: institutions such as the National Museums of Kenya, the Nairobi National Museum, and the Kenya National Theatre showcase archaeology, natural history, and performing arts. The city is proximate to protected areas including Nairobi National Park, where wildlife such as lions and giraffes coexist near urban development, and to attractions like the David Sheldrick Wildlife Trust and Giraffe Centre. Markets like Kenyatta Market and cultural festivals featuring music, literature, and film connect to regional networks such as African Union cultural initiatives. Architectural landmarks include the KICC (Kenya International Conference Centre), the Moi International Sports Centre, and colonial-era buildings in central districts.

Transportation and urban planning

Transport infrastructure centers on Jomo Kenyatta International Airport and a network of roads, commuter rail lines, and bus rapid transit proposals aimed at reducing congestion. The Standard Gauge Railway and commuter rail services link the city to coastal and inland hubs, while highways such as the A104 road form arterial routes. Urban planning efforts address informal settlements such as Kibera and Mathare, with upgrading programs and mixed-use development proposals promoted by agencies including UN-Habitat and the World Bank. Contemporary projects seek to integrate transit-oriented development, green spaces, and flood mitigation along riparian corridors to enhance resilience and livability.
