After forced migration to a country where immigrants form an ethnic majority, why do some individuals support exclusivist and nationalist political parties while others do not? Based on extensive interviews and an original survey of 1200 local Serbs and ethnic Serbian refugees fleeing violent conflict in Bosnia and Croatia, this book adds the dimension of ethnic identity to the analysis of individual political behaviour, without treating ethnic groups as homogeneous social categories. It adds valuable insight to the existing literature on political behaviour by emphasizing the role of social ties among individuals.
