Dwelling in the highland areas of Cambodia, Laos, Vietnam, Thailand, Burma (Myanmar) and southwest China are hundreds of ethnic groups known as ‘tribes’ in popular literature. Some groups number barely more than one hundred, others millions. Together their population adds up to 80 million, more than any of the countries (bar China) they inhabit, yet in each they are designated and treated as “minorities.” They have been forced to dwell in the highlands while their enemies have occupied the more fertile lowlands. This, coupled with the fact that they are so little known abroad and even at home, has caused their way of life and cultural distinctions to come in jeopardy.This book offers hundreds of cross-referenced dictionary entries on about 200 groups, the six countries they live in, some of their leaders, and their political, economic, social, cultural and religious aspects. The chronology covers important events. The introduction discusses both the diversities and similarities of the groups’ ethnicities, languages, religious practices, and customs. And the bibliography supplements the dictionary entries.
