This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book focuses on the reactions of Swedish Jews and their responses to the Nazi's anti-Jewish measures, viewed in relation to official Swedish and international responses to these atrocities. It also focuses on local, national, and international politics and on the organization and agency of the Jewish minority in Sweden. The book addresses the problem of agency and the limitations to Jewish minorities' efforts to aid their brethren, the policies and actions concerning refugee aid, relief and political actions such as attempts to exert pressure in order to make the Swedish Government and others intervene to aid Jews. It examines to what extent the policies and actions of Swedish Jews towards Nazi terror depended on the policies and actions of states, intergovernmental institutions, and other organizations in Sweden and abroad.
