The Chaga (also called Wachaga, Chagga, Jagga, Dschagga, Waschagga, or Wachagga) are Bantu-speaking indigenous Africans and the third largest ethnic group in Tanzania. They live on the southern and eastern slopes of Mount Kilimanjaro and Mount Meru, as well as in the Moshi area. Their relative wealth comes from not only the favorable climate of the area, but also from successful agricultural methods which include extensive irrigation systems and continuous fertilization practiced for thousands of years. They were one of the first tribes in the area to convert to Christianity. This may have given them an economic advantage over other ethnic groups, as they had better access to education and health care as Christians. The Chagga descend from various Bantu groups who migrated from the rest of Africa into the foothills of Kilimanjaro. While the Chagga are Bantu-speakers, they do not speak a single language but rather a number of related Chagga dialects.
