In 1954, Julius Nyerere and Oscar Kambona transformed the Tanganyika African Association (founded in 1929) into the more politically oriented Tanganyika African National Union (TANU). TANU easily won the general elections of 1958–60, and when Tanganyika became independent on Dec. 9, 1961, Nyerere became its first prime minister. In Dec. 1962, Tanganyika became a republic within the Commonwealth of Nations, and Nyerere was made president. On Apr. 26, 1964, shortly after a leftist revolution in newly independent Zanzibar, Tanganyika and Zanzibar merged; Nyerere became the new country’s first president. Abeid Amani Karume, the head of Zanzibar’s government and leader of its dominant Afro-Shirazi party (ASP), became Tanzania’s first vice president. Although formally united with the mainland, Zanzibar retained considerable independence in internal affairs. In Feb. 1967, Nyerere issued the Arusha Declaration, a major policy statement that called for egalitarianism, socialism, and self-reliance. It promised a decentralized government and a program of rural development called ujamaa (“pulling together”) that involved the creation of cooperative farm villages. Factories and plantations were nationalized, and major investments were made in primary schools and health care. While Nyerere put some of the declaration’s principles into practice, it was not clear if the power in Tanzania was, in fact, being decentralized. TANU was the mainland’s sole legal political party and it was tightly controlled by Nyerere. In the early 1970s, there was tension (and occasional border clashes) between Tanzania and Uganda, caused mainly by Nyerere’s continued support of Uganda’s ousted president, A. Milton Obote. However, in 1973, Nyerere and Gen. Idi Amin, Uganda’s new head of state, signed an agreement to end hostilities. Tanzania supported various movements against white-minority rule in S Africa, and several of these organizations had offices in Dar-es-Salaam. In 1977, TANU and Zanzibar’s ASP merged to form the Party of the Revolution (CCM). A new constitution was adopted the same year. Hostilities with Uganda resumed in 1978 when Ugandan military forces occupied about 700 sq mi (1800 sq km) of N Tanzania and left only after having caused substantial damage. One month later, Tanzanian forces and Ugandan rebels staged a counter-invasion. Tanzania captured the Ugandan capital of Kampala in 1979 and drove Idi Amin from power. This campaign further depleted the country’s already scarce economic resources. Tanzania maintained troops in Uganda after its victory and drew criticism from other African nations for its actions. In 1983, negotiations between Kenya, Tanzania, and Uganda led to the reopening of the Kenyan border, which had been closed since 1977 after the collapse of the East African Community.
Tanzania has a tropical climate but has regional variations due to topography. In the highlands, temperatures range between 10 and 20 °C (50 and 68 °F) during cold and hot seasons respectively. The rest of the country has temperatures rarely falling lower than 20 °C (68 °F). The hottest period extends between November and February (25–31 °C or 77.0–87.8 °F) while the coldest period occurs between May and August (15–20 °C or 59–68 °F). Seasonal rainfall is driven mainly by the migration of the Intertropical Convergence Zone. It migrates southwards through Tanzania from October to December, reaching the south of the country in January and February, and returning northwards in March, April, and May. This causes the north and east of Tanzania to experience two distinct wet periods – the short rains (or “Vuli”) in October to December and the long rains (or “Masika”) from March to May – while the southern, western, and central parts of the country experienced one wet season that continues October through to April or May. The onset of the long rains averages 25 March and the cessation averages 21 May. A warmer-than-normal South Atlantic Ocean coupled with a cooler-than-normal Eastern Indian Ocean often causes the onset to be delayed. Of the land area, 84.1% has a tropical wet and dry/ savanna climate (Aw), 6.9% has a semi-arid/ steppe climate (BS), 9% has a temperate/ mesothermal climate with dry winters (Cw). Of the population, 80.5% live in a tropical wet and dry/ savanna climate (Aw), 9.5% live in a semi-arid/ steppe climate (BS), 10% live in a temperate/ mesothermal climate with dry winters (Cw)
Tanzanians are warm-hearted and generous people and are eager to help visitors get the most out of their stay. Hotels are safe and have watchmen. Tanzania is a politically stable, multi-democratic country. However, as in all countries, a little common sense goes a long way and reasonable precautions should still be taken, such as locking valuables in the hotel safe and not walking alone at night.
