Tanzania is a developing East African nation noted for its history of stability and astounding natural beauty. A robust tourism industry provides all levels of tourist amenities, although higher-end facilities are concentrated mainly in the cities and selected game parks. The United Republic of Tanzania was formed in 1964 with the union of the mainland country of Tanganyika and the Zanzibar archipelago, which includes the islands of Unguja and Pemba. Unguja is the much larger and populous of the two islands and is commonly referred to as Zanzibar. The main city of Zanzibar is known as Stone Town. Although part of the union government, Zanzibar has its own president, court system, and legislature, and exercises considerable autonomy. The U.S. Embassy is in Tanzania’s largest city, Dar es Salaam, the location of most government offices, all embassies, and the commercial center of the country.
