the Hadza people
The Hadza, or Hadzabe, are an indigenous ethnic group in north-central Tanzania, living around Lake Eyasi in the central Rift Valley and in the neighboring Serengeti Plateau. There are, as of 2015, between 1,200 and 1,300 Hadza people living in Tanzania, although the increasing impact of tourism and encroaching pastoralists pose serious threats to the continuation of their traditional way of life.
Genetically, the Hadza are not closely related to any other people. While traditionally classified with the Khoisan languages, primarily because it has clicks, the Hadza language appears to be an isolate, unrelated to any other. As descendants of Tanzania's aboriginal hunter-gatherer population, they have probably occupied their current territory for thousands of years, with relatively little modification to their basic way of life until the past hundred years.
Since the 18th century, the Hadza have come into increasing contact with farming and herding people entering Hadzaland and its vicinity; the interactions often were hostile and caused population decline in the late 19th century. The first European contact and written accounts of the Hadza are from the late 19th century. Since then, there have been many attempts by successive colonial administrations, the independent Tanzanian government, and foreign missionaries to settle the Hadza, by introducing farming and Christianity. These efforts have largely failed, and many Hadza still pursue virtually the same way of life as their ancestors are described as having in early 20th-century accounts. In recent years, they have been under pressure from neighbouring groups encroaching on their land, and also have been affected by tourism and safari huntin
