In three consecutive studies and a summarizing final report, Klaus Biedermann, Nicole Schwalbach, Veronika Marxer, and Regula Argast narrate the fluctuating history of naturalization in Liechtenstein from the early 19th century to the present day. In the tension between local peculiarities and international connections, they outline the development of the economically significant municipal citizenship in the 19th century, the financial naturalization between 1920 and 1955, and the civic integration of long-established foreign residents after 1945.
