Pre-history

It is estimated that hominids lived in Botswana during the Pleistocene. Stone tools and animal remains indicate that all areas of the country were inhabited at least 400,000 years ago.

It was claimed to have been the birthplace of all modern humans from around 200,000 years ago. Evidence left by modern humans, such as cave paintings, is about 73,000 years old. The earliest known inhabitants of southern Africa are thought to have been the forebears of present-day San ("Bushmen") and Khoi peoples. Both groups speak click languages from the small Khoe-Kwadi, Kx’a and Tuu families whose members hunted, gathered, and traded over long distances. When cattle were first introduced about 2000 years ago into southern Africa, pastoralism became a major feature of the economy since the region had large grasslands free of tsetse flies.

It is unclear when Bantu -speaking peoples first moved into the country from the north, although AD 600 seems to be a consensus estimate. In that era the ancestors of the modern-day Kalanga moved into what is now the north-eastern area of the country. These proto-Kalanga were closely connected to states in Zimbabwe as well as to the Mapungubwe state, and the notable of these was Domboshaba ruins, a cultural and heritage site in Botswana initially occupied towards the end of the Great Zimbabwe period (1250–1450), with stone walls that have an average height of 1.8 metres. The site is a respected place for the people living in the region, and it is believed that the chief lived on the top of the hill with his helpers or assistants. These states, located outside of current Botswana's borders, appear to have kept massive herds of cattle in what is now the Central District—apparently at numbers approaching modern cattle density. This massive cattle-raising complex prospered until 1300 or so and seems to have regressed following the collapse of Mapungubwe. During this era the first Tswana-speaking groups, the Bakgalagadi, moved into the southern areas of the Kalahari. All these various peoples were connected to trade routes that ran via the Limpopo River to the Indian Ocean, and trade goods from Asia such as beads made their way to Botswana, most likely in exchange for ivory, gold and rhinoceros horn.

Toutswemogala Hill Iron Age Settlement's radio-carbon dates for this settlement range from the 7th to late 19th century indicating occupation of more than one thousand years. The hill was part of the formation of early states in Southern Africa with cattle keeping as a major source of economy. Toutswe settlement includes house-floors, large heaps of vitrified cow dung and burials while the outstanding structure is the stone wall. Around 1000 AD, the Toutswe people moved into Botswana.

However, agriculture also played a vital role in the longevity of Toutswemogala Hill's extended occupation, as many grain storage structures have also been found on the site. Many different stratified layers of housing floors further signal continuous occupation over hundreds of years. The arrival of the ancestors of the Tswana speakers who came to control the region has yet to be dated precisely. Members of the Bakwena, a chieftaincy under a leader named Kgabo II, made their way into the southern Kalahari by AD 1500, at the latest, and his people drove the Bakgalagadi inhabitants west into the desert. Over the years, several offshoots of the Bakwena moved into adjoining territories. The Bangwaketse occupied areas to the west, while the Bangwato moved northeast into formerly Kalanga areas. Not long afterwards, a Bangwato offshoot known as the Batawana migrated into the Okavango Delta, probably in the 1790s.
