History of Nairobi County

The city of Nairobi was founded in 1899 by the British colonial government as a railway depot for the Uganda Railway. The name “Nairobi” is derived from the Maasai phrase “Enkare Nairobi,” which means “cool water.” The British colonial government chose the city’s location because it was a major watering hole for the Maasai people and was conveniently located along the railway line.

During the early years of the city’s development, Nairobi was a small, dusty outpost with little infrastructure. However, in the 1920s and 1930s, the city experienced a rapid growth spurt as it became the administrative centre of British East Africa.
