The first of the ‘modern’ (still present today) ethnic groups of Zambia to arrive were the Tonga and Ila peoples (sometimes combined as the Tonga-Ila), who migrated from the Congo area in the late 15th century. By 1550 they had occupied the Zambezi Valley and plateau areas north of where Lake Kariba is now – and which is still their homeland today. Next to arrive were the Chewa. Between the 14th and 16th centuries they followed a long and circuitous route via Lakes Mweru, Tanganyika and Malawi before founding a powerful kingdom covering much of present-day eastern Zambia, as well as parts of Malawi and Mozambique. Today the Chewa are still the largest group in eastern Zambia.

The Bemba (most notably the ruling Ngandu clan) had migrated from Congo by crossing the Luapula River into northern Zambia by around 1700. Meanwhile, the Lamba people migrated to the area of the Copperbelt in about 1650. At around the same time, the related Lala settled in the region around Serenje.

In western Zambia, the Lozi people established a dynasty and the basis of a solid political entity that still exists. The Lozi’s ancestors may have migrated from what is now Angola as early as AD 450.

Early 19th Century

In the early 19th century, the fearsome reputation of the newly powerful and highly disciplined warrior army under the command of Shaka Zulu in KawZulu Natal (South Africa) led to a domino effect as groups who lived in his path fled elsewhere and in turn displaced other groups. This included the Ngoni, who fled to Malawi and Zambia, as well as the Makololo who moved into southern Zambia, around the towns of Kalomo and Monze, and who were eventually forced further west into southwest Zambia, where they displaced more Tonga people.

Also around this time, the slave trade, which had existed for many centuries, increased considerably. Swahili-Arabs, who dominated the trade on the east coast of Africa, pushed into the interior; many people from Zambia were captured and taken across Lake Malawi and through Mozambique or Tanzania to be sold in the slave markets of Zanzibar.

The Colonial Era

David Livingstone, the Scottish explorer, journeyed through large swaths of Zambia, including the lower Zambezi, where he came upon a magnificent waterfall never before seen by a European, naming it Victoria Falls in homage to royalty back home. On a subsequent trip, Livingstone died while searching for the source of the Nile in northern Zambia. His heart was buried under a tree near the spot where he died, in Chief Chitambo's village, southeast of Lake Bangweulu.

In 1885 claims over African territory by European powers were settled at the Berlin Conference and the continent was split into colonies and spheres of influence – Britain claimed Rhodesia (Zambia and Zimbabwe) and Malawi.

This ‘new’ territory did not escape the notice of entrepreneur Cecil John Rhodes, who was already establishing mines and a vast business empire in South Africa. Rhodes’ British South Africa Company (BSAC) laid claim to the area in the early 1890s and was backed by the British government in 1895 to help combat slavery and prevent further Portuguese expansion in the region.

Two separate territories were initially created – North-Western Rhodesia and North-Eastern Rhodesia – but these were combined in 1911 to become Northern Rhodesia. In 1907 Livingstone became the capital. At around the same time, vast deposits of copper were discovered in the area now called the Copperbelt.

In 1924 the colony was put under direct British control and in 1935 the capital was moved to Lusaka. To make them less dependent on colonial rule, settlers soon pushed for closer ties with Southern Rhodesia and Nyasaland (Malawi), but various interruptions (such as WWII) meant that the Federation of Rhodesia and Nyasaland did not come about until 1953.

Independence & Kaunda

In Zambia the United National Independence Party (UNIP) was founded in the late 1950s by Dr Kenneth Kaunda, who spoke out against the federation on the grounds that it promoted the rights of white settlers to the detriment of the indigenous African population. As other African countries gained independence, Zambian nationalists opposed colonial forces through civil disobedience and a small but decisive conflict called the Chachacha Rebellion.

Northern Rhodesia became independent a year after the federation was dissolved and changed its name to Zambia. While the British government had profited enormously from Northern Rhodesia, the colonialists chose to spend a large portion of this wealth on the development of Southern Rhodesia (now Zimbabwe).

After gaining independence, Zambia inherited a British-style multiparty political system. Kaunda, as leader of the majority UNIP, became the new republic’s first president. The other main party was the African National Congress (ANC), led by Harry Nkumbula. But Kaunda disliked opposition. In one swift move during 1972, he disbanded the Zambian ANC, created the ‘second republic’, declared UNIP the sole legal party and made himself the only presidential candidate.

Consequently Kaunda remained in power for the next 27 years. His rule was based upon ‘humanism’ – his own mix of Marxism and traditional African values. The civil service was increased, and nearly all private businesses (including the copper mines) were nationalised. But corruption and mismanagement, exacerbated by a fall in world copper prices, doomed Zambia to become one of the poorest countries in the world by the end of the 1970s. The economy continued to flounder, and Zambia’s trade routes to the coast through neighbouring countries (such as Zimbabwe and Mozambique) were closed in retaliation for Kaunda’s support for several liberation movements in the region.

By the early 1980s Rhodesia gained independence (to become Zimbabwe), which allowed Kaunda to take his country off a war footing, and the Tazara railway to Dar es Salaam (Tanzania) was completed, giving Zambia unencumbered access to the coast. Yet the economy remained on the brink of collapse: foreign-exchange reserves were almost exhausted, serious shortages of food, fuel and other basic commodities were common, and unemployment and crime rates rose sharply.

In 1986 an attempt was made to diversify the economy and improve the country’s balance of payments. Zambia received economic aid from the International Monetary Fund (IMF), but the IMF conditions were severe and included cutting basic food subsidies. Subsequent price rises led to country-wide riots in which many people lost their lives. Kaunda was forced to restore subsidies.

The winds of change blowing through Africa during the late 1980s, coupled with Zambia’s disastrous domestic situation, meant that something had to give. Following another round of violent street protests against increased food prices in 1990, which quickly transformed into a general demand for the return of multiparty politics, Kaunda was forced to accede to public opinion.

He announced a snap referendum in late 1990 but, as protests grew more vocal, he was forced to legalise opposition parties and announce full presidential and parliamentary elections for October 1991. Not surprisingly, UNIP (and Kaunda) were resoundingly defeated by the Movement for Multiparty Democracy (MMD), led by Frederick Chiluba, a former trade-union leader. Kaunda stepped down without complaint, which may have saved Zambia from descending into anarchy.

The 1990s

President Chiluba moved quickly to encourage loans and investment from the IMF and World Bank. Exchange controls were liberalised to attract investors, particularly from South Africa, but tough austerity measures were also introduced. Once again food prices soared. The civil service was rationalised, state industries privatised or simply closed, and thousands of people lost their jobs.

By the mid-1990s the government's failure to bring about any perceptible improvements to the economy and the standard of living in Zambia allowed Kaunda to confidently re-enter the political arena. He attracted strong support and soon became the UNIP leader. Leading up to the 1996 elections, the MMD panicked and passed a law forbidding anyone with foreign parents to enter politics (Kaunda’s parents were from Malawi). Despite intercessions from Western aid donors and world leaders like Nelson Mandela – not to mention accusations that Chiluba’s parents were from the Democratic Republic of the Congo (Zaïre) – the law was not repealed. The UNIP withdrew all its candidates in protest and many voters boycotted the election. Consequently Chiluba and the MMD easily won, and the result was grudgingly accepted by most Zambians.

In the 21st Century

The political shenanigans continued unabated at the start of the new millennium: in mid-2001 vice-president Christon Tembo was expelled from parliament by Chiluba, so he formed an opposition party – the Forum for Democratic Development (FDD). Later, Paul Tembo, a former MMD national secretary, joined the FDD but was assassinated the day before he was due to front a tribunal about alleged MMD corruption.

Chiluba was unable to run for a third presidential term in December 2001 (though he badly wanted to change the Constitution so he could). He anointed his former vice-president, Levy Mwanawasa, as his successor, but Mwanawasa only just beat a coalition of opposition parties known as the United Party for National Development (UPND). Again, allegations from international observers about the MMD rigging the results and buying votes fell on deaf ears. To Chiluba’s horror, Mwanawasa stripped his predecessor of immunity from prosecution and proceeded to launch an anti-corruption drive, which targeted the former president. In August 2009, after a long-running trial, Chiluba was cleared of embezzling US$500,000 by Zambia’s High Court. His wife, however, was not so lucky, having been given a jail term earlier in the year for receiving stolen funds while her husband was in office. In a separate case in 2007, the High Court in Britain ruled Chiluba and four of his aides conspired to rob Zambia of about US$46 million, but in Zambia he was acquitted of such charges in 2009. Only two years later he passed away from a heart attack, aged 68.

Although Zambia remains a poor country, its economy experienced strong growth in the early part of the 21st century with GDP growing at around 6%. However, the country is still very dependent on the world prices of its principal minerals (copper and cobalt).

As well as combating global markets, natural disasters have played a significant role in the country’s fortunes. Although a bumper harvest was recorded in 2007, floods in 2008–09 were declared a national disaster and killed dozens of people – the Zambezi River, which flooded much of western Zambia, was said to be at its highest level in 60 years, and crops were severely affected.

In September 2011, Michael Sata, nicknamed 'King Cobra', and his party the Patriotic Front (PF) won national elections. The populist strain in Sata's policy was apparent by his decision to revalue the country's currency. Motivated more by symbolism than economics, it was a move that indicated a sincere focus on redirecting the country's wealth to the majority of Zambians who remained impoverished. He also announced a significant increase in the minimum wage in September 2012, and his administration encouraged Zambian participation and ownership in the tourism industry. However, his presidency was tainted by heavy-handed tactics to clamp down on political opposition. Sata passed away while still in power on 28 October 2014 after battling a long illness, plunging Zambia into a period of political uncertainty and leaving his successor with numerous political, economic and environmental challenges.
