In the first book to explore the theory and practice of eugenics in the American South, Edward Larson shows how the quest for "strong bloodlines" expressed itself in specific state laws and public policies from the Progressive Era through World War II. Presenting new evidence of race-based and gender-based eugenic practices in the past, Larson also explores issues that remain controversial today - including state control over sexuality and reproduction, the rights of disabled persons and of ethnic minorities, and the moral and legal questions raised by new discoveries in genetics and medicine. Larson shows how the seemingly broad-based eugenics movement was in fact a series of distinct campaigns for legislation at the state level - campaigns that could often be traced to the efforts of a small group of determined individuals. Explaining how these efforts shaped state policies, he places them within a broader cultural context by describing the workings of Southern state legislatures, the role played by such organizations as women's clubs, and the distinctly Southern cultural forces that helped or hindered the implementation of eugenic reforms.
