The Ilchamus (sometimes spelled Camus or Iltiamus, also known as Njemps), are a Maa-speaking people living south and southeast of Lake Baringo, Kenya. They number about 35,000 and are closely related to the Samburu living more to the north-east in the Rift Valley Province. Their language is one of the Eastern Nilotic Maa languages, closely related to the Samburu language (between 89% and 94% lexical similarity), to the point of it being considered a Samburu dialect by some. Together, Samburu and Ilchamus form the northern division of the Maa languages.
In their oral traditions, the Ilchamus economy underwent a succession of elaborations: from foraging and fishing to a sophisticated system of irrigation, and then this was mixed with pastoralism under the influence of Samburu immigrants and neighbouring Maasai. These changes involved a series of embellishments in their culture and social organization. However, this evolving system did not survive the challenges of the capitalist economy in post-colonial Kenya, leading to a more polarized society with diminishing prospects for the majority of Camus.
