Southward-migrating Bantu farmers and herders settled in the area that is now Zambia over a period of several centuries beginning around the 4th century ad. These forerunners of the Sotho and Nguni groups developed mining and metalworking techniques. A new group, the Shona Bantu, arrived in the 12th century. Later, the Karanga clan of the Shona established the great empire of the Mwene Mutapa, which included southern Zambia. In the 17th and 18th centuries, the Lunda and Lozi from the Congo (now the DRC) populated the northern plains and upper Zambezi River area. In the 19th century, the Kololo, fleeing the wars in South Africa, moved northward and established brief control over much of central and northern Zambia before the Lozi once again asserted their dominance. Eastern Zambia was settled by Bantu peoples related to those in Malawi. Despite their differences, these various Bantu groups shared certain common characteristics. They were primarily agriculturists, but most of them also kept cattle. They were tribally oriented, and their states usually were small, except when a dominant king, such as the ruler of the Karanga, Kololo, or Lozi, imposed his will on neighboring tribes. Consequently, when the British moved into Zambia—or Barotseland, as they called it—in the latter part of the 19th century, no powerful kingdoms were there to resist them.

Stone tools attributable to early types of man have been found near the Victoria Falls and in the far northeast, near Kalambo Falls. In 1921, excavations at Kabwe revealed the almost complete skull of Homo sapiens rhodesiensis (“Broken Hill Man”), which may be well over 100,000 years old. However, by 20,000 BC the only surviving type of human throughout the Old World was the ancestor of modern man, Homo sapiens sapiens, who developed the use of spears, the bow and arrow, game traps, and grindstones. Remains of such industries have been found in much of central and northern Zambia, sometimes near lakes and rivers but often in caves and rock-shelters.

The federation was dissolved at the end of 1963. Nyasaland became independent as Malawi in July 1964, and Northern Rhodesia as Zambia in October 1964. Southern Rhodesia changed its name to Rhodesia. Kaunda’s party, the United National Independence Party (UNIP), won the first and all subsequent elections until the early 1990s. In 1972 Zambia became a one-party state, but its leadership remained moderate and pro-Western. Private land was nationalized in 1975 as part of an unsuccessful agricultural improvement program. The completion of the rail link to Dar es Salaam, Tanzania, in 1976, freed Zambia from its dependence on the Rhodesian- and South African-controlled railway for the transport of its copper.
