Tanzania IPA: [tænzəˈniə], officially the United Republic of Tanzania (Swahili: Jamhuri ya Muungano wa Tanzania), is a country in East Africa 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. Tanganyika united with Zanzibar in 1964, forming the United Republic of Tanganyika and Zanzibar, which later the same year was renamed the United Republic of Tanzania.
