A good read - http://www.africa.upenn.edu/afrfocus/afrifocus010808.html An excerpt: "For most people in Western countries, Africa immediately calls up the word "tribe." The idea of tribe is ingrained, powerful, and expected. Few readers question a news story describing an African individual as a tribesman or tribeswoman, or the depiction of an African's motives as tribal. Many Africans themselves use the word "tribe" when speaking or writing in English about community, ethnicity or identity in African states. Yet today most scholars who study African states and societies--both African and non-African--agree that the idea of tribe promotes misleading stereotypes. The term "tribe" has no consistent meaning. It carries misleading historical and cultural assumptions. It blocks accurate views of African realities. At best, any interpretation of African events that relies on the idea of tribe contributes no understanding of specific issues in specific countries. At worst, it perpetuates the idea that African identities and conflicts are in some way more "primitive" than those in other parts of the world. Such misunderstanding may lead to disastrously inappropriate policies."
