Possibly Africa’s most famous ethnic group, the Maasai people are semi-nomadic people located primarily in Kenya and Northern Tanzania. According to their own oral history the Masai people originated in the Nile Valley in Northern Africa and migrated south around the 15th century with their cattle. They quickly spread south through the Rift Valley where the fertile grasslands were ideal for their cattle and around the 18th century, reached the present-day territories in Kenya and Tanzania.
