McGilvray explores the densely populated farming and fishing settlements in this coastal zone, focusing on the Tamil and Muslim inhabitants of an agricultural town in the Ampara District. Drawing on fieldwork conducted over more than thirty years as well as on Tamil and Dutch historical sources, he describes the regional dominance of a non-Brahmin matrilineal caste of thirteenth-century Kerala origin. The Muslims, who acquired dowry lands and matrilineal family patterns through local intermarriages, have in the twentieth century emerged from Hindu caste domination and are now the Tamil Hindus’ political and economic equals. Crucible of Conflict offers a uniquely detailed account of Muslim kinship and community organization in eastern Sri Lanka, as well as a comparison of Tamil and Muslim practices and institutions. McGilvray concludes with an analysis of the interethnic tensions and communal violence that have intensified in recent years.
