Dedan Kimathi Waciuri (31 October 1920 18 February 1957), born Kimathi wa Waciuri in what was then British Kenya, was the senior military and spiritual leader of the Mau Mau Uprising. Widely regarded as a revolutionary leader, he led the armed military struggle against the British colonial regime in Kenya in the 1950s until his capture in 1956 and execution in 1957. Kimathi is credited with leading efforts to create formal military structures within the Mau Mau, and convening a war council in 1953. He, along with Musa Mwariama and Muthoni Kirima, was one of three Field Marshals.

Kenyan nationalists view him as the heroic figurehead of the Kenyan freedom struggle against British colonial rule, while the British government saw him as a terrorist. Despite being viewed with disdain by the first two presidents of independent Kenya, Jomo Kenyatta and Daniel arap Moi, Kimathi and his fellow Mau Mau rebels were officially recognised as heroes in the struggle for Kenyan independence under the Mwai Kibaki administration, culminating in the unveiling of a Kimathi statue in 2007. This was reinforced by the passage of a new Constitution in 2010 calling for recognition of national heroes.

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.
