Tanzania has a long history of tribal habitation stretching back to our most distant ancestors. Tribal migrations, occurring between 3,000 to 5,000 years ago, brought agricultural and pastoral knowledge to the area as competing tribal groups spread over the country in search of fertile soil and plentiful grazing for their herds.
European missionaries and explorers mapped the interior of the country by following well-worn caravan routes, including Burton and Speke who in 1857 journeyed to find the source of the Nile. Traditional ways of life remained largely intact until the arrival of German colonisers in the late 19th century.
On the Swahili Coast, Indian Ocean trade began as early as 400 BC between Greece and Azania, as the area was commonly known. Around the 4th century AD, coastal towns and trading settlements attracted Bantu-speaking peoples from the African hinterland. They settled around mercantile areas and often facilitated trading with the Arabs and Persians, who bartered for slaves, gold, ivory, and spices, sailing north with the monsoon wind. Between the 13th and 15th centuries, the civilisations of Kilwa Kisiwani and the Zanzibar Archipelago reached their peak, with a highly cosmopolitan population of Indian, Arab, and African merchants trading in luxury goods that reached as far as China. The completion of Portuguese domination in 1525 meant that trade, for a short time, was lessened, but rival Omani Arab influences soon took control of the caravan routes and regained complete control of the islands, even going so far as to make Zanzibar the capital of Oman in the 1840s.
In the late 19th century, British influence in the Zanzibar Archipelago, in contrast to German influence on the Tanzanian mainland, slowly suppressed the slave trade and brought the area under the influence of the Empire. Local rebellions in German East Africa, most notably the Maji Maji rebellion from 1905 to 1907, slowly weakened the coloniser’s grip on the nation, and at the end of the First World War Germany ceded Tanganyika to English administration. Under the leadership of Julius Nyerere, popularly referred to as Mwalimu, or ‘teacher,’ Tanganyika achieved full independence in 1962. Meanwhile, a popular revolution in Zanzibar ousted the Omani Arabs and established majority rule in 1963. A year later, the United Republic of Tanzania was formed, unifying the Tanganyika mainland with the semi-autonomous islands of the Zanzibar Archipelago.
Engaruka
Mysterious ruins of complex irrigation systems span the area around Engaruka, the remnants of a highly developed but unknown civilisation that inhabited the area at least 500 years ago – and then vanished without a trace.
Kilwa Kisiwani
The island of Kilwa Kisiwani and the nearby ruins of Songo Mnara is among the most important remnants of Swahili civilization on the East African coast. The area became the center point of Swahili civilisation in the 13th century when it controlled the gold trade with Sofala, a distant settlement in Mozambique. In the 14th century, Arab traveller Ibn Battuta described Kilwa as being exceptionally beautiful and well-developed. After a brief decline under the rule of the Portuguese, Kilwa once again became a center of Swahili trade in the 18th century, when slaves were shipped from its port to the islands of Comoros, Mauritius, and Réunion.
Lindi
The port town of Lindi, in south-western Tanzania, was the final stop for slave caravans from Lake Nyasa during the heyday of the Zanzibari sultans. In 1909, a team of German paleontologists unearthed the remains of several dinosaur bones in Tendunguru, including the species Brachiosaurus brancai, the largest discovered dinosaur in the world.
Mikindani
Another central port in the Swahili Coast’s network of Indian Ocean trade, in the 15th century Mikindani’s reach extended as far as the African hinterlands of the Congo and Zambia. The area became a center of German colonial administration in the 1880s and a chief exporter of sisal, coconuts, and slaves.
Ngorongoro Conservation Area
Humans and their distant ancestors have been part of Ngorongoro’s landscape for millions of years. The earliest signs of mankind in the Conservation Area are at Laetoli, where hominid footprints are preserved in volcanic rock 3.6 million years old. The story continues at Olduvai Gorge, a river canyon cut 100 m deep through the volcanic soil of the Serengeti Plains. Buried in the layers are the remains of animals and hominids that lived and died around a shallow lake amid grassy plains and woodlands. These remains date from two million years ago. Visitors can learn more details of this fascinating story by visiting the site, where guides give a fascinating on-site interpretation of the gorge.
