In Contested Rituals, Robin Judd shows that circumcision and kosher butchering became focal points of political struggle among the German state, its municipal governments, Jews, and Gentiles. In 1843, some German-Jewish fathers refused to circumcise their sons, prompting their Jewish communities to reconsider their standards for membership. Nearly a century later, in 1933, another blood ritual, kosher butchering, served as a political and cultural touchstone when the Nazis built upon a decades-old controversy concerning the practice and prohibited it. In describing these events and related controversies that raged during the intervening years, Judd explores the nature and escalation of the ritual debates as they transcended the boundaries of the local Jewish community to include non-Jews who sought to protect, restrict, or prohibit these rites.
