18,000,000 BCE – 99
Where humankind learned to make tools
Lomekwi, Koobi Fora, Turkana Boy, Olorgesailie and the Stone Age foragers of the Rift Valley and Lake Turkana basin.
Large flaked cobbles from Lomekwi 3, dated to about 3.3 million years ago and announced in 2015, push toolmaking back before the genus Homo.
Kamoya Kimeu's find of 1984 at Nariokotome produced the most complete early human skeleton known, about 1.6 million years old.
Bantu-speaking farmers and ironworkers settled near Lake Victoria about 500 BCE, joining the herders already in the Rift.
100 – 1497
Stone towns on the monsoon
Cushitic, Nilotic and Bantu migrations, and the stone towns of Gedi, Shanga, Lamu and Mombasa on the Indian Ocean trade.
By the eleventh century a Swahili culture of stone towns and Islam traded ivory, timber and slaves for cloth, glass and beads.
Ibn Battuta stayed a night in Mombasa about 1331 and described a city of orchards and pious Muslims.

Vasco da Gama reached Mombasa on 7 April 1498 and, a week later, found an ally in the sultan of Malindi.
The Portuguese began the fortress in 1593; Omani forces took it on 13 December 1698 after a siege of almost three years.
Rebmann sighted Kilimanjaro in 1848 and Krapf sighted Mount Kenya in 1849, to the doubt of European geographers.
1888 – 1919
Company, railway and capital
The IBEA Company, the Uganda Railway, Nairobi, the white highlands, resistance and the First World War.
The Uganda Railway began at Mombasa on 30 May 1896 and gave Kenya its spine.

The Crown Lands Ordinance of 1902 opened the highlands to settlers; Koitalel arap Samoei was killed on 19 October 1905.
1920 – 1952
Settlers, land and the first politics
Settlers, land and labour, Thuku and the KCA, Kenyatta, the Second World War and rising nationalism.
On 23 July 1920 the interior became the Colony of Kenya, with the coastal strip a separate protectorate.
Thuku's arrest on 14 March 1922 brought a crowd to Nairobi's police lines and a shooting on 16 March.

From the skull of a Miocene ape on Rusinga Island and the oldest stone tools yet found at Lomekwi to the coral-stone lanes of Lamu, the bastions of Fort Jesus, the railway that created Nairobi, the forests of the Mau Mau fighters and the runners of the Rift Valley, Kenya has left the world evidence of the earliest toolmakers, one of the great Indian Ocean trading cultures, a settler colony and the rebellion against it, a constitution with forty-seven counties, and a record of protest and reform that runs from Harry Thuku in 1922 to the young demonstrators of 2024, between Koobi Fora, Mombasa, Nairobi, Kisumu, Eldoret, Zanzibar, Lisbon, Muscat, London and The Hague.
Kenyan sites have repeatedly rewritten the story of human origins. Mary Leakey found a nearly complete Proconsul skull, about 18 million years old, on Rusinga Island on 2 October 1948; Bernard Ngeneo of Richard Leakey's team found the fragments of Skull 1470 at Koobi Fora in 1972; and in 1984 Kamoya Kimeu spotted the fragment that led to the Turkana Boy, the most complete early human skeleton known, about 1.6 million years old, at Nariokotome. At Lomekwi 3 in West Turkana, a team led by Sonia Harmand and Jason Lewis announced in 2015 large flaked cobbles and anvils dated to about 3.3 million years ago, older than any other known stone tools.
Olorgesailie and Kariandusi preserve the hand-axe workshops of Homo erectus, Enkapune Ya Muto holds some of the world's oldest ostrich eggshell beads, about 40,000 years old, and the rock art of Kakapel and the pillar sites of Namoratunga record the foragers and herders who followed. UNESCO inscribed the Lake Turkana National Parks, which include the Koobi Fora fossil beds, and Mount Kenya, sacred to the Kikuyu, Embu and Meru, in 1997.
The monsoon tied the coast of Kenya to Arabia, India and China for two thousand years. The Periplus of the Erythraean Sea describes the coast of Azania about 40–70 CE, Ibn Battuta stayed a night in Mombasa about 1331 and found it a large island city of orchards and pious Muslims, and the stone towns of Shanga, Manda, Gedi and Ungwana traded ivory and mangrove poles for cloth, beads and Chinese porcelain. Lamu town grew from the fourteenth century into a centre of Islamic scholarship and Swahili poetry, and its old town was inscribed by UNESCO in 2001 as the oldest and best preserved Swahili settlement in East Africa.
Malindi sent a giraffe to the Ming court in 1414, and Zheng He's fleet called on the coast about 1417–1419. Vasco da Gama reached Mombasa on 7 April 1498 and allied with the sultan of Malindi a week later; the Portuguese began Fort Jesus in 1593, designed by Giovanni Battista Cairati, and held it until Imam Saif bin Sultan's Omani forces took it on 13 December 1698 after a siege of almost three years. The Mazrui of Mombasa, Seyyid Said's move of his capital to Zanzibar in 1840 and the clove and ivory economy that rested on slavery followed, until the treaties of 1845 and 1873 and the British protectorate; Fort Jesus has been a UNESCO site since 2011.
Cushitic herders reached the Rift about 1500 BCE and Bantu farmers and iron workers settled near Lake Victoria about 500 BCE; Nilotic and Maa-speaking pastoralists followed. Kikuyu tradition places the nine clans' founders, Gikuyu and Mumbi, at Mukurwe wa Nyagathanga in Murang'a, and their farmers cleared the forests of the Mount Kenya foothills; the Kamba led ivory caravans to Mombasa; the Nandi and other Kalenjin built age-set societies in the western highlands; the Maasai expanded across the Rift Valley and were reshaped by the Iloikop wars; Luo-speaking groups moved toward Lake Victoria; and the Mijikenda settled in fortified kayas, several of which are now UNESCO sites.
Their histories rest largely on oral tradition and linguistics, and the dates are approximate. When Johannes Rebmann glimpsed snow on Kilimanjaro on 11 May 1848 and Johann Ludwig Krapf sighted Mount Kenya, called Kirinyaga by his Kamba companions, from near Kitui on 3 December 1849, Europe doubted them; by the 1880s Joseph Thomson and Count Teleki had crossed these lands, and the Heligoland-Zanzibar Treaty of 1 July 1890 drew a line between British and German spheres across communities such as the Maasai and the Taita.
The Imperial British East Africa Company received its charter on 3 September 1888, and Britain proclaimed the East Africa Protectorate on 1 July 1895. Work on the Uganda Railway began at Mombasa on 30 May 1896; critics called it the Lunatic Express, and the maneaters of Tsavo halted the bridge-building in 1898. The railway reached the cool plain the Maasai called Enkare Nyrobi at Mile 327 on 30 May 1899, and Nairobi grew from a depot into the capital; it reached Kisumu on Lake Victoria on 20 December 1901.
To pay for the line, the Crown Lands Ordinance of 1902 allowed the sale of land not in African occupation, and the Anglo-Maasai Treaty of 10 August 1904 moved the Maasai to reserves. The Colony of Kenya was proclaimed on 23 July 1920, the Devonshire White Paper of 1923 declared African interests paramount, and the Carter Land Commission of 1933 confirmed the White Highlands. Resistance ran from the Nandi orkoiyot Koitalel arap Samoei, killed on 19 October 1905, and Mekatilili wa Menza's Giriama movement of 1913–1914 to Harry Thuku's East African Association of 1921 and the Kikuyu Central Association of 1924, which Jomo Kenyatta served as general secretary from 1928.
On 20 October 1952 Governor Evelyn Baring declared a state of emergency against the Mau Mau movement, and the Kapenguria trial convicted Kenyatta and five colleagues on 8 April 1953. The Emergency brought detention camps, villagisation and Operation Anvil, the sweep of Nairobi on 24 April 1954; Dedan Kimathi was captured on 21 October 1956 and hanged at Kamiti on 18 February 1957; and the beating of detainees at Hola camp on 3 March 1959, in which eleven men died, caused a political crisis in London. The dead of Lari in 1953 and of the camps are remembered differently by different Kenyans, and on 6 June 2013 Britain announced compensation for 5,228 Kenyans tortured or abused in detention.
The first Lancaster House conference opened on 18 January 1960 and accepted the principle of African majority rule; Kenyatta was released on 14 August 1961, KANU won the 1963 election, internal self-government came on 1 June 1963, independence on 12 December 1963 and the republic, with Kenyatta as president and Oginga Odinga as vice-president, on 12 December 1964. Tom Mboya's student airlift of 1959–1961 took hundreds of Kenyans to American universities, among them Wangari Maathai.
The Kenyatta years saw the Shifta War, the murder of Tom Mboya on 5 July 1969, the Kisumu massacre of 25 October 1969 and the banning of the Kenya People's Union. Daniel arap Moi succeeded on Kenyatta's death on 22 August 1978, introduced the Nyayo philosophy, and after the air force coup attempt of 1 August 1982 made Kenya a de jure one-party state under Section 2A; the Nyayo House cells, the Saba Saba protest of 7 July 1990 and the repeal of Section 2A in December 1991 mark the road to multiparty politics. The embassy bombing of 7 August 1998 killed about 213 people, and Mwai Kibaki was sworn in on 30 December 2002.
The disputed election of 27 December 2007 led to violence that left more than a thousand dead (sources differ on the toll), the National Accord of 28 February 2008 created a coalition with Raila Odinga as prime minister, and the constitution promulgated on 27 August 2010 introduced a bill of rights, a Supreme Court, a Senate and forty-seven counties, whose governors took office from 27 March 2013. The International Criminal Court cases against Uhuru Kenyatta and William Ruto ended in 2014 and 2016; the Supreme Court annulled the August 2017 presidential election on 1 September 2017; and the Finance Bill protests of 2024, the impeachment of Deputy President Rigathi Gachagua on 17 October 2024 and the death of Raila Odinga on 15 October 2025 mark the most recent turns.
Kip Keino won the 1500 metres at the Mexico City Olympics on 20 October 1968, training at altitude in the Rift Valley, and Eldoret, Iten and Kaptagat became the training grounds of a nation of distance runners. Eliud Kipchoge won the world 5000 metres title in Paris in 2003 and ran 1:59:40 in Vienna on 12 October 2019, a time not ratified as a record because of pacemakers and other aids. Wangari Maathai, founder of the Green Belt Movement, won the Nobel Peace Prize on 8 October 2004, the first African woman to do so.
Tsavo became a national park in 1948, Kenya burned about twelve tonnes of confiscated ivory on 18 July 1989, and the Kenya Wildlife Service was created under Richard Leakey. Nairobi has hosted the United Nations Environment Programme since 1972, and Safaricom launched the M-Pesa mobile-money service nationwide in March 2007, one of the models of financial inclusion that gave the capital its name of Silicon Savannah. The Danish writer Karen Blixen lived near the Ngong Hills from 1914 to 1931, and the film of her memoir, Out of Africa, won the Best Picture Oscar in 1986.
