This open access book discusses how national citizenship is being transformed by economic
social and political change. It focuses on the emergence of global markets where citizenship is
for sale and on how new reproduction technologies impact citizenship by descent. It also
discusses the return of banishment through denationalisation of terrorist suspects and the
impact of digital technologies such as blockchain on the future of democratic citizenship.
The book provides a wide range of views on these issues from legal scholars political
scientists and political practitioners. It is structured as a series of four conversations in
which authors respond to each other. This exchange of arguments provides unique depth to
current debates about the future of citizenship.
