Tanganyika (now Tanzania) is the cradle of mankind. In 1959 in the north of the country, in the Olduvai Gorge, Dr. Louis Leakey discovered the fossilized remains of Zinjanthropus calculated to be 1.75 million years old, the forerunner of modern man. South of Olduvai Gorge, a trail of hominid foot prints 3,600,000 years ago were discovered at Laoteli only 30 kilometers from Olduvai Gorge. Tanzania is home of about 126 African tribes, the majority being of Bantu origin who migrated into Tanzania from West and Central Africa. While in Tanzania, they assimilated most of the people of Khoisan and Cushitic origin who had been there since the 3rd and 1st centuries BC respectively. Very few groups of people of these origins (Khoisan and Cushitic) remain in Tanzania today. Besides peoples of Bantu, Cushitic and Khoisan origin, there are also groups of Nilotic origin the most famous being the Maasai. These are said to have settle in Tanzania in the 1st century AD. On the other hand, the Ngoni tribe, fleeing from "mfecane" (the times of troubles) brought about by the Zulu expansion under their famous King, Shaka, entered southwestern Tanzania in 1840 and defeated the Fipa who moved to northwestern Tanzania.
