Political trust – in government, parliament, or political parties – has taken centre stage in political science for more than half a century, reflecting ongoing concerns with the legitimacy and functioning of representative democracy. To provide scholars, students and policy makers with a tool to navigate through the complexity of causes and consequences of political trust, this Handbook offers an excellent overview of the conceptual, theoretical, methodological and empirical state of the art, complemented by accounts of regional particularities, and authored by international experts in this field.
