Recent events have shown mature democracies beset by threats to constitutionalism and human rights. This panel brings global and comparative perspectives to bear on this phenomenon. Along with internationally prominent events like the United Kingdom‘s decision to leave the European Union, this panel examines new challenges facing societies that tend to be less frequently discussed or are even touted as success stories, such as South Korea. By exploring these cases in conversation with each other, panel participants aim to gain better understanding of recent crosscurrents between democracy, constitutionalism, and human rights in global and comparative contexts. Important themes include nationalistic sentiments and attitudes and institutions hostile to non-citizens, as well as broader questions about political community, citizenship, solidarity, and inclusion.
