Population Description: First appearing in oral history in the 1880s, they are derived from a group of poor Rendille and Samburu groups who banded together to build up their herds in the mountains. Culturally, they still exhibit features of both Rendille and Samburu, including Samburu age-set rituals and Rendille annual camel blessings.

Ariaal derive their subsistence from herding camels, cattle, goats, and sheep, which they depend on for nutrition in the form of milk, blood, and meat. In more recent times some Ariaal have settled and begun to practice agriculture.
