Tanzania, officially the United Republic of Tanzania, is a country in East Africa. It is bordered by Kenya and Uganda to the north; Rwanda, Burundi, and the Democratic Republic of the Congo to the west; and Zambia, Malawi, and Mozambique to the south. The country's eastern border is formed by the Indian Ocean. Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania.
The country is divided into 30 administrative regions: five on the semi-autonomous islands of Zanzibar and 25 on the mainland in the former Tanganyika. The head of state is President Jakaya Mrisho Kikwete, elected in 2005. Since 1996, the official capital of Tanzania has been Dodoma, where the National Assembly and some government offices are located. Between independence and 1996, the main coastal city of Dar es Salaam served as the country's political capital. It remains Tanzania's principal commercial city and is the main location of most government institutions. It is also the principal port of the country.
The name "Tanzania" derives from the names of the two states, Tanganyika and Zanzibar, that united on 26 April 1964 to form the United Republic of Tanganyika and Zanzibar. On 29 October 1964, the country was renamed the United Republic of Tanzania. The Articles of Union are the main foundation of Tanzania.
