Nairobi

Nairobi is a young city built where no town stood before. In 1899 the Uganda Railway, pushing inland from Mombasa, reached a swampy watering place on the plains that the Maasai called Enkare Nyirobi, "cool water", and the railway company set up its depot and workshops there, at the point where the line faced the climb to the highlands. Within a few years the tented camp had become a town, and in 1907 it replaced Mombasa as the capital of the British East Africa Protectorate.

Colonial Nairobi was planned in racial zones: a European quarter on the higher, cooler ground to the west and north, an Asian commercial district around the bazaar, and African workers' housing in the east, with most of the African population living as labourers with no security of tenure. Plague outbreaks in the early years led to whole quarters being burned and rebuilt. The city became the administrative and social centre of settler Kenya, and during the Emergency of the 1950s it was also a centre of the Mau Mau struggle: in Operation Anvil in 1954 the security forces sealed the city and screened tens of thousands of Kikuyu residents, sending many to detention camps.

Independence came in 1963, and Nairobi grew very fast as restrictions on movement ended. It gained the headquarters of the United Nations Environment Programme in 1972, the first such agency based in the developing world, and became the base for regional business, aid agencies and media. The city has also carried hard days — the bombing of the United States embassy in August 1998, post-election violence in 2007 and 2008, later attacks on public places, and the protests of 2024 and 2025 — alongside a long building boom that has filled Upper Hill and Westlands with towers.

Nairobi is the meeting point of every Kenyan community, and that mixing is the city's defining cultural fact. Its young people speak Sheng, a fast-changing slang built from Swahili, English and the vocabularies of the estates, which travels outward through music and radio. Nairobi's music scene runs from gospel, the largest-selling music in the country, through benga and mugithi to genge and the hard, chanted gengetone that came out of the eastern estates.

The matatu is a cultural form in its own right. The minibuses are painted with portraits of footballers, musicians and preachers, fitted with sound systems and screens, and competed over by crews who make routes into a kind of street theatre. Wall murals and graffiti, much of it political, follow the same tradition.

The city supports theatre, stand-up comedy, a long-running literary culture and a contemporary art scene with galleries in Kilimani, Karen and the centre. Football and athletics dominate conversation, and rugby sevens has a following of its own. Religion is public and important: churches of every size fill Sunday mornings and mosques serve the eastern districts, and church and mosque networks organise much of the city's charity and mutual aid, in the Harambee spirit of pulling together. Manners are formal by regional standards — greetings first, titles used, and open anger avoided.

Nairobi had about 4.3 million people at the 2019 census and an estimated 4.8 million in 2024, and the built-up area spreads well beyond it into Kiambu and Machakos, so that towns such as Ruiru and Ngong function as suburbs. The economy is the most diversified in East Africa: government, banking and insurance, the offices of the United Nations and hundreds of international organisations, media, horticulture and a technology sector that grew out of the success of M-Pesa mobile money.

The contrasts are sharp. Karen, Muthaiga and Runda have large houses in wooded gardens; the middle-income estates of Kileleshwa, South B and Kasarani fill with flats; and perhaps a third or more of residents live in informal settlements, Kibera and Mathare the best known, where housing, water and sanitation are insecure. Rents in the better-served areas have risen steeply.

The day begins very early. Matatus fill before dawn because the roads into the centre seize up soon afterwards, and the evening peak lasts for hours; commuting is the single biggest complaint of city life, along with the cost of living and the price of unga, maize flour. Many families keep land upcountry and travel to it at Christmas and Easter. Evenings are for nyama choma with friends, church midweek services, football on television in local bars, and, for the young, a nightlife in Westlands and Kilimani that runs late.

Nairobi eats from the whole country. Nyama choma — goat or beef roasted over charcoal, chopped on a wooden board and eaten by hand with ugali, the stiff maize porridge, and kachumbari, a salad of tomato, onion and chilli — is the city's social meal, ordered by the kilo in butcheries and garden bars.

Everyday food is cheap and filling: githeri, boiled maize and beans; mukimo, a mash of potato, greens and maize from the surrounding highlands; beans or lentils with chapati; and sukuma wiki, braised collard greens whose name means "push the week". Workers' cafés serve mandazi, lightly sweet fried dough, with chai, the strong sweet milky tea that is the national drink. Street food means mutura, a grilled sausage of meat and blood, smokies with kachumbari from handcarts, roasted maize cobs and chips mwitu, deep-fried potatoes cooked at the roadside.

Migration has given the city its other kitchens: Indian food from a community present since the railway years, from biryani to bhajia; Somali and Ethiopian restaurants in Eastleigh and Kilimani; and coastal Swahili cooking with coconut and spice. Tusker lager is the standard beer, fresh tree-tomato and passion juices are everywhere, and a strong café culture has grown up around the coffee the highlands around the city produce.
