The Hadza, or Hadzabe (Wahadzabe, in Swahili), are a protected hunter-gatherer Tanzanian indigenous ethnic group, primarily based in Baray, an administrative ward within Karatu District in southwest Arusha Region. They live around the Lake Eyasi basin in the central Rift Valley and in the neighboring Serengeti Plateau. As descendants of Tanzania's aboriginal, pre-Bantu expansion 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 last century. They have no known close genetic relatives and their language is considered an isolate.
Since the first European contact in the late 19th century, governments and missionaries have made many attempts to settle the Hadza by introducing farming and Christianity. These efforts have largely failed, and many Hadza still pursue a life similar to their ancestors. Since the 18th century, the Hadza have come into increasing contact with pastoralist peoples entering Hadzaland, sometimes declining in population. Tourism and safari hunting have also affected them in recent years.
