History of Botswana

The history of Botswana encompasses the region's ancient and tribal history, its colonisation as the Bechuanaland Protectorate, and the present-day Republic of Botswana. The first modern humans to inhabit Botswana were the San people, and agriculture first developed approximately 2,300 years ago. The first Bantu peoples arrived c. 200 AD, and the first Tswana people arrived about 200 years later. The Tswana people split into various tribes over the following thousand years as migrations within the region continued, culminating in the Difaqane in the late 18th century. European contact first occurred in 1816, which led to the Christianization of the region.

Facing threats from German South West Africa and the Afrikaners, the most influential Tswana chiefs negotiated the creation of a protectorate under the United Kingdom in 1885. The British divided the territory into tribal reserves for each of the major chiefs to rule, giving the chiefs more power than they had previously, but it otherwise exercised only limited direct control over the protectorate. The British government took a more active role beginning in the 1930s. Botswana supported British involvement in World War II and many fought as part of the African Auxiliary Pioneer Corps.

A power struggle took place in the 1950s between the Ngwato chief Seretse Khama and his regent Tshekedi Khama. Seretse's marriage to a white woman, Ruth Williams Khama, led the British to ban him from the protectorate. He returned in 1956 with popular support, and tribes moved toward elected government as an independence movement formed. A national legislature was created in 1961, and political parties were formed. Seretse became the leader of the Bechuanaland Democratic Party, which was endorsed by the British government to lead post-independence, and it saw overwhelming support in the first election in 1965. The Republic of Botswana was granted full independence in 1966.

With a strong mandate, Seretse and his party implemented liberal democracy and began developing infrastructure in what was one of the world's poorest nations. Extensive diamond deposits were discovered in 1969, causing a massive reorganisation of Botswana's economy. The Debswana mining company was created in 1978, and Botswana became the world's fastest growing economy. The HIV/AIDS pandemic became a crisis in Botswana in the 1980s, and the 1990s came with the introduction of political factionalism after the political scandal of the Kgabo Commission. Political conflict within the Botswana Democratic Party continued over the following decades with a split occurring in 2010 and the exile of former president Ian Khama at the behest of his protege Mokgweetsi Masisi in 2021.
