Ivan Ermakoff ’s Ruling Oneself Out focuses on two major instances of voluntary surrender of power in Western history: the March 1933 bill that empowered Adolf Hitler with the right to amend the Weimar Constitution and the transfer of full executive, legislative, and constitutional authority to Marshal Philippe Pétain in July 1940. The first event inaugurated the Third Reich, the other Vichy France. Much ink has been spilled over these events. But Ermakoff finds various problems with the existing accounts and advances his own theory of collective abdication in their stead. Moreover, his theory is geared to analyze all kinds of political crises and breakdowns where collective abdication plays a role—as it often does in such contexts. Ermakoff ’s theory is a formal one. It can hold for any situation in which a group confronts the possibility of collective persecution and has to decide whether to resist or abdicate. It is not confined to formally defined collectivities or to parliamentary settings: the dynamics that it reveals are independent of specific group configurations and institutional contexts.
