In contrast to most other countries, both Germany and Israel have descent-based concepts of nationhood and have granted members of their nation (ethnic Germans and Jews) who wish to immigrate automatic access to their respective citizenship privileges. Therefore these two countries lend themselves well to comparative analysis of the integration process of immigrant groups, who are formally part of the collective self but increasingly transformed into others. This volume offers rich empirical and theoretical material involving historical developments, demographic changes, sociological problems, anthropological insights, and political implications. Focusing on the three dimensions of citizenship: sovereignty and control, the allocation of social and political rights, and questions of national identity, the essays bring to light the elements that are distinctive for either society but also point to similarities that owe as much to nation-specific characteristics as to evolving patterns of global migration.
