What is the history of Tanzania?

The United Republic of Tanzania has a rich history, dating back millions of years, and is the 13th
largest country in Africa. Its Olduvai Gorge region is called “The Cradle of Mankind.” Here,
researchers have found 3.6-million-year-old footprints from our immediate human ancestors, the
Laetoli.
Tanzania (its name) is the combination of Tanganyika and Zanzibar. On 26th April 1964, the two
regions unified, forming the United Republic of Tanzania after becoming free from British colonial
rule. The same year, Prime Minister Mwalimu Julius K. Nyerere became president of Tanzania and
introduced African socialism to promote justice and equality.
