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 traditionally live on the southern and eastern slopes of Mount Kilimanjaro and Mount Meru and near Moshi. Their relative wealth comes from the favorable climate of the area and successful agricultural methods, which include extensive irrigation systems, terracing, and continuous organic fertilization methods 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.
