Tanzania is one of the birthplaces of ancient humans. In the 7th to 8th centuries, Arabs and Persians migrated in large numbers. In 1886, the mainland of Tanganyika was designated as a German sphere of influence. In 1890, Zanzibar became a British protectorate, and in November 1917, the entire territory was under British control. After World War I, it became a British appointed territory. After World War II, the United Nations resolution changed the mainland of Tanganyika to a British “trust territory”. After a long period of struggle, the people of Tanganyika and Zanzibar officially declared independence on December 9, 1961 and January 12, 1964, respectively. On April 26, 1964, the United Republic of Tanganyika and Zanzibar was formed, and on October 29, it was renamed the United Republic of Tanzania.
