Tanzania IPA: [?tænz?'ni?], officially the United Republic of Tanzania (Jamhuri ya Muungano wa Tanzania in Swahili), is a country on the east coast of Africa. It is bordered by Kenya and Uganda on the north, Rwanda, Burundi and the Democratic Republic of the Congo on the west, and Zambia, Malawi and Mozambique on the south. To the east it borders the Indian Ocean. The country is named after Tanganyika, its mainland part, and the Zanzibar islands off its east coast. The country has been a member of the Commonwealth since gaining independence in 1961. In 1964, Tanganyika united with Zanzibar, forming the United Republic of Tanganyika and Zanzibar, later renamed to the United Republic of Tanzania. In 1996, Tanzania's capital was officially moved from Dar es Salaam to Dodoma, although many government offices still remain in the old capital.
