This book is the first comprehensive examination of the citizenship regimes of the new states that emerged out of the break up of Yugoslavia. It covers both the states that emerged out of the initial disintegration across 1991 and 1992 (Slovenia, Croatia, Bosnia-Herzegovina, the Federal Republic of Yugoslavia and Macedonia), as well as those that have been formed recently through subsequent partitions (Serbia, Montenegro and Kosovo). While citizenship has often been used as a tool of ethnic engineering to reinforce the position of the titular majority in many states, in other cases citizenship laws and practices have been liberalised as part of a wider political settlement intended to include minority communities more effectively in the political process. Meanwhile, frequent (re)definitions of these increasingly overlapping regimes still provoke conflicts among post-Yugoslav states.
