Tanzania

• 1. Introduction

  ›

  Tanzania does not have an official language by law, yet over 100 languages are spoken inside its borders, more than any other country in East Africa. Among them sit four of Africa's language families: Bantu, Cushitic, Nilotic, and Khoisan. The country's very name was invented in a newspaper contest, stitched together from two states that had been separate colonies until 1964. One man named Mohammed Iqbal Dar won that contest. He took the syllables Tan and Zan, added the i from his own name, and finished with an a. This is a nation assembled from fragments, then deliberately fused into one identity by a single president. How did a German colony, a British territory, and an Arab-ruled island archipelago become one republic of roughly 67.5 million people? What does a country do when it contains around 120 ethnic groups and wants none of them to define it? And how did a place where iron was forged at staggering heat more than 1,500 years ago become one of Africa's busiest safari destinations? The answers run from the floor of Africa's deepest lake to the snowcap of its highest mountain.

• 2. A Name Stitched Together

  ›

  Mohammed Iqbal Dar said he drew the final a in Tanzania as a reference to Ahmadiyya. The rest came from Tanganyika and Zanzibar, the two states that united in 1964. The national newspaper The Standard had run the naming contest, and Dar's entry won. Tanganyika carries its own buried meaning in Swahili. The word tanga means sail, and nyika means uninhabited plain or wilderness, so the name reads as sail in the wilderness. It is sometimes taken as a reference to Lake Tanganyika itself. Zanzibar reaches back further, into older trading languages. It derives from Zanj, the name of a local people, joined with the Arabic word barr, meaning coast or shore. Zanj in turn comes from Al-Zanjia, the Arabic name for the East African coast. That same coast appears in a first-century text, the Periplus of the Erythraean Sea, under the Greek name Azania, described as ruled by the Mapharitis, a people who lived in what is now southwest Yemen. The coast had a name in foreign mouths long before it had a country.

• 3. Iron, Trade, And Kilwa

  ›

  The Haya people on the western shores of Lake Victoria invented a high-heat blast furnace that forged carbon steel at temperatures above 1820 degrees Celsius, more than 1,500 years ago. The Pare people, in the mountains of north-eastern Tanzania, were the main producers of the iron that surrounding peoples sought. This was a region working metal at a sophisticated level deep in the first millennium. On the coast, a different kind of wealth was taking shape. At Fukuchani, on the north-west coast of Zanzibar, archaeologists found a settled farming and fishing community dating to at least the 6th century. Timber buildings, shell beads, bead grinders, and iron slag mark the site, alongside a small amount of imported pottery, less than 1 percent of the finds, mostly from the Gulf. Trade grew sharply from the mid-8th century. By the close of the 10th century, Zanzibar had become one of the central Swahili trading towns. Power gathered in Kilwa, Tanzania's major medieval city-state, which controlled smaller ports stretching down toward modern-day Mozambique. Kilwa grew rich as gold from Sofala passed through, while its rivals Mombasa and Malindi lay to the north. Kilwa held its position as the major power in East Africa until the Portuguese arrived at the end of the 15th century.

• 4. Empire And The Slave Coast

  ›

  In 1840, the Omani Sultan Said bin Sultan moved his capital to Zanzibar City, and the island became the centre of the East African slave trade. Between 65 and 90 percent of Zanzibar's African population was enslaved. The historian Timothy Insoll records the exporting of 718,000 slaves from the Swahili coast during the 19th century, with 769,000 retained on the coast. One of the most infamous traders was Tippu Tip, while Nyamwezi slave traders operated under leaders named Msiri and Mirambo. Slavery was abolished in the 1890s. Germany conquered the mainland regions, minus Zanzibar, in 1885, folding them into German East Africa. The colony bred violent resistance. The Maji Maji Rebellion, between 1905 and 1907, united several African tribes against forced labour and deportation. The repression, combined with famine, killed 300,000 people out of a Tanganyikan population of about four million. German rule ended with World War I. On the 7th of May 1919, the Supreme Council of the Paris Peace Conference awarded the colony to Britain. Through a series of negotiated agreements that year, the north-western provinces of Ruanda and Urundi went to Belgium, and the small Kionga Triangle south of the Rovuma River went to Portuguese Mozambique. On the 10th of January 1920, the territory passed officially to Britain, and the name Tanganyika was born.

• 5. Nyerere And One Identity

  ›

  In 1954, Julius Nyerere transformed an organisation into the Tanganyika African National Union, or TANU, aimed at national sovereignty. Within a year of launching a membership drive, TANU had become the country's leading political organisation. Nyerere became a minister in 1960 and prime minister when Tanganyika gained independence in 1961. British rule formally ended on the 9th of December 1961. Elizabeth II, who had taken the British throne in 1952, reigned through that first year as Queen of Tanganyika, represented by a governor general. On the 9th of December 1962, the territory became a democratic republic under an executive president. Zanzibar's path was bloodier. The Zanzibar Revolution overthrew the island's Arab dynasty, with the slaughter of thousands of Arab Zanzibaris, and on the 26th of April 1964 the archipelago merged with the mainland. On the 29th of October that year, the combined state was renamed the United Republic of Tanzania. Facing more than 130 languages and around 120 groups, Nyerere set out to build a single national identity. The result is regarded as one of the most successful cases of ethnic repression and identity transformation in Africa. Ethnic divisions stayed rare here, unlike in neighbouring Kenya, and the country held more political stability than most on the continent.

• 6. Ujamaa And The Cold War

  ›

  The 1967 Arusha Declaration turned Nyerere's first presidency to the left, codifying a commitment to socialism and Pan-Africanism. Banks and many large industries were nationalised. His socialist ideology, called Ujamaa, emphasised collective ownership, rural development, and the idea that growth should benefit the whole population rather than a small elite. It was an African form of socialism, rooted in traditional village life rather than the industrial, state-centred models of the Soviet Union. That distinction set Tanzania apart, since several other African nations adopted foreign ideologies during the Cold War. Non-alignment let Tanzania take aid from rivals at once. The United States, the Soviet Union, and China all supplied aid, though Tanzanians never declared allegiance to any of them. Between 1970 and 1975, China financed and helped build the 1860 kilometre TAZARA Railway, running from Dar es Salaam to Kapiri Mposhi in Zambia. The economy soured anyway. From the late 1970s it weakened amid an international crisis, and in 1978 neighbouring Uganda, under Idi Amin, invaded. Tanzania struck back with the help of Ugandan rebels and deposed Amin, but the war badly damaged its economy. From the mid-1980s the regime borrowed from the International Monetary Fund and undertook reforms, and gross domestic product per capita has grown and poverty fallen since.

• 7. One Party, Many Presidents

  ›

  In 1992, on the 1st of July, the constitution was amended to allow multiple parties, ending the legal monopoly that the Chama Cha Mapinduzi had held since independence. CCM is the longest-serving ruling party in Africa. In the first multi-party elections in 1995, it won 186 of the 232 elected National Assembly seats, and Benjamin Mkapa became president. The line of presidents since independence runs from Julius Nyerere, who served from 1962 to 1985, through Ali Hassan Mwinyi, Mkapa, Jakaya Kikwete, and John Magufuli, to Samia Suluhu Hassan from 2021. A two-term limit of five years each was set after Nyerere's long tenure, and every president has come from CCM. The main opposition party since 1992 is Chama cha Demokrasia na Maendeleo, or Chadema, led by Freeman Mbowe. Magufuli won re-election in October 2020 with the national commission reporting 84 percent, while opposition candidate Tundu Lissu received 13 percent. The opposition alleged fraud. On the 17th of March 2021, Magufuli died in office, and his vice president, Samia Suluhu Hassan, became Tanzania's first female president. She was declared the winner of the 2025 general elections with 98 percent of the vote, after barring the two main opposition parties. Protests erupted, and authorities met them with lethal force that left hundreds killed and many more maimed.

• 8. Lakes, Peaks, And Wildlife

  ›

  Mount Kilimanjaro rises 5895 metres above sea level, the highest point in Africa and the highest single free-standing mountain above sea level in the world. The country also holds Africa's lowest point, the floor of Lake Tanganyika, at 1471 metres below sea level. Three of Africa's Great Lakes lie partly within Tanzania: Lake Victoria, the continent's largest, Lake Tanganyika, its deepest and home to unique fish species, and Lake Nyasa to the south. The Kalambo Falls, on the Zambian border, is the second highest uninterrupted waterfall in Africa. This landscape carries an extraordinary share of the continent's animal life. Tanzania holds about 20 percent of the species of Africa's large mammal populations, spread across 21 national parks plus reserves, conservation areas, and marine parks. It has the largest lion population in the world, around 130 amphibian species, and over 275 reptile species, many of them strictly endemic. On the Serengeti plain, white-bearded wildebeest, other bovids, and zebra join a large annual migration. In western Tanzania, Gombe Stream National Park was where Jane Goodall began her study of chimpanzee behaviour in 1960. Tourism rewards all of this. In 2016, 1,284,279 tourists arrived at the country's borders, compared with 590,000 in 2005, and most head for Zanzibar or the northern circuit anchored by the Serengeti.
