Hadzabe Bushman and Datoga tribe at the Lake Eyasi, Tanzania

The Hadza, or Hadzabe, are an ethnic group in north-central Tanzania, living around Lake Eyasi in the central Rift Valley and in the neighboring Serengeti Plateau. 

The Hadza number just under 1000. Some 300--400 Hadza live as hunter-gatherers, much as their ancestors have for thousands or even tens of thousands of years; they are the last full-time hunter-gatherers in Africa.

The Datoga consider themselves the oldest tribe in Tanzania. The Datoga are first and foremost warrior's, known for their stealth ability to eliminate their enemy. Little is know or archived about the Datoga. It is known that they migrated some 3000 years ago from the Highlands of Ethiopia. Datoga's are farmers specializing in onion plantations, but share similarities to Maasai in some traditions. 

They are characteristically known for keeping to themselves. Datoga consider anyone other than Datogan an enemy. They refused to engage themselves in colonization and vehemently resent the government, making them an enemy of the state. However, their current situation has placed them in a pivotal challenge of continuing their traditional existence. 

An ongoing challenge has been Datoga's poor attention to health and education but has been slowly changing. Until recently only 5% of Datoga spoke the national language Swahili. The current challenges facing Datoga are the intrusion of other tribes for tourism and investment purposes, cutting of trees for making coal, Maasai stealing their cows, and the government selling land and moving the Datoga to drier pastures. Datoga's resistance to peace partnering with other tribes has made it difficult to create empathy for their cause.
