In 1877, the American Humane Society was formed as the national organization for animal and child protection. Thirty years later, there were 354 anticruelty organizations chartered in the United States, nearly 200 of which were similarly invested in the welfare of both humans and animals. In The Rights of the Defenseless, Susan J. Pearson seeks to understand the institutional, cultural, legal, and political significance of the perceived bond between these two kinds of helpless creatures, and the attempts made to protect them. 160; Unlike many of today8217;s humane organizations, those Pearson follows were delegated police powers to make arrests and bring cases of cruelty to animals and children before local magistrates. Those whom they prosecuted were subject to fines, jail time, and the removal of either animal or child from their possession. Pearson explores the limits of and motivation behind this power and argues that while these reformers claimed nothing more than sympathy with the helpless and a desire to protect their rights, they turned 8220;cruelty8221; into a social problem, stretched government resources, and expanded the state through private associations. The first book to explore these dual organizations and their storied history, The Rights of the Defenseless will appeal broadly to reform-minded historians and social theorists alike.
