The 2009 Nakumatt supermarket fire occurred when a supermarket in downtown Nairobi, Kenya, caught fire on 28 January 2009. Twenty-nine remains have thus far been located in the rubble of the destroyed Nakumatt supermarket, with police investigating a tip that security guards locked exit doors in an effort to prevent looting. However the locking of the doors on the ground floor had no effect on the victims, as they were all found on the floor above. The fire allegedly started near the only staircase accessible to the public, trapping the victims in the shop. One other man died after leaping from the building to escape the flames. Forty-seven people are still missing. The bodies of the dead are "charred beyond recognition".Official reports say one person died in hospital from injuries brought on by poisonous fumes and injuries sustained in the inferno but another 39 were unaccounted for and were officially reported as "missing". The emergency services were criticised for what the Kenyan media viewed as an inadequate response to the blaze. Following the blaze, the Daily Nation reported that Nairobi's three million inhabitants were served only by one fire station situated close to a traffic-choked business district. Although it happened on 28 January, it was not widely reported across the world until two days later when the full scale of the fire was recognised.

Kenya, officially the Republic of Kenya (Swahili: Jamhuri ya Kenya), is a country in Eastern Africa. At 580,367 square kilometres (224,081 sq mi), Kenya is the world's 48th largest country by area. With a population of more than 47.6 million in the 2019 census, Kenya is the 29th most populous country in the world. Kenya's capital and largest city is Nairobi, while its oldest, currently second largest city, and first capital is the coastal city of Mombasa. Kisumu City is the third-largest city and also an inland port on Lake Victoria. Other important urban centres include Nakuru and Eldoret. As of 2020, Kenya is the third-largest economy in sub-Saharan Africa after Nigeria and South Africa. Kenya is bordered by South Sudan to the northwest, Ethiopia to the north, Somalia to the east, Uganda to the west, Tanzania to the south, and the Indian Ocean to the southeast. Its geography, climate and population vary widely, ranging from cold snow-capped mountaintops (Batian, Nelion and Point Lenana on Mount Kenya) with vast surrounding forests, wildlife and fertile agricultural regions to temperate climates in western and rift valley counties and dry less fertile arid and semi-arid areas and absolute deserts (Chalbi Desert and Nyiri Desert).

Kenya's earliest inhabitants were hunter-gatherers, like the present-day Hadza people. According to archaeological dating of associated artifacts and skeletal material, Cushitic speakers first settled in Kenya's lowlands between 3,200 and 1,300 BC, a phase known as the Lowland Savanna Pastoral Neolithic. Nilotic-speaking pastoralists (ancestral to Kenya's Nilotic speakers) began migrating from present-day South Sudan into Kenya around 500 BC. Bantu people settled at the coast and the interior between 250 BC and 500 AD. European contact began in 1500 AD with the Portuguese Empire, and effective colonisation of Kenya began in the 19th century during the European exploration of the interior. Modern-day Kenya emerged from a protectorate established by the British Empire in 1895 and the subsequent Kenya Colony, which began in 1920. Numerous disputes between the UK and the colony led to the Mau Mau revolution, which began in 1952, and the declaration of independence in 1963. After independence, Kenya remained a member of the Commonwealth of Nations. The current constitution was adopted in 2010 to replace the 1963 independence constitution.

Kenya is a presidential representative democratic republic, in which elected officials represent the people and the president is the head of state and government. Kenya is a member of the United Nations, Commonwealth of Nations, World Bank, International Monetary Fund, COMESA, International Criminal Court, and other international organisations. With a GNI of 1,460, Kenya is a lower-middle-income economy. Kenya's economy is the largest in eastern and central Africa, with Nairobi serving as a major regional commercial hub. Agriculture is the largest sector: tea and coffee are traditional cash crops, while fresh flowers are a fast-growing export. The service industry is also a major economic driver, particularly tourism. Kenya is a member of the East African Community trade bloc, though some international trade organisations categorise it as part of the Greater Horn of Africa. Africa is Kenya's largest export market, followed by the European Union.
