Once a rare phenomenon, multiple state membership and multinational citizenship has become almost commonplace with the rise in transnational mobility. This compilation analyses transnational participation focusing mainly on the interests of individual people and their transnational networks. The focus lies on the perceptions, attitudes, experiences and views on membership and participation of people with dual/multiple citizenship and individuals with multinational background who hold a single citizenship. Eight contributions present findings from the international research project Dual Citizenship, Governance and Education: A Challenge to the European Nation-State (DCE) conducted in 2002-2006 in Britain, France, Portugal, Germany, Finland, Greece, Estonia, and Israel.
