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, The Politics of Social Ties argues that those immigrants who form close interpersonal networks with others who share their experiences, such as the loss of family, friends, and home, in addition to the memory of ethnic violence from past wars, are more likely to vote for nationalist parties. Any political mobilization occurring within these interpersonal networks is not strategic, rather, individuals engage in political discussion with people who have a greater capacity for mutual empathy over the course of discussing other daily concerns. This book adds the dimension of ethnic identity to the analysis of individual political behavior, without treating ethnic groups as homogeneous social categories. It adds valuable insight to the existing literature on political behavior by emphasizing the role of social ties among individuals.
