The situation of internally displaced persons has been a matter of international concern - and legal debate - since at least the late 1990s and early 2000s, and its salience has only increased in the context of extreme weather events produced by intensifying climate change. Research in political philosophy, however, has so far barely touched on this issue, despite its close connection to and relevance for lively and expansive debates on migration, refugees, territorial rights, state sovereignty, and climate change. This volume aims to set the philosophical agenda for articulating a political ethics of internal displacement, and to highlight the importance of the phenomenon for these wider theoretical issues. Across 12 chapters that explore different aspects of internal displacement, authors working at the forefront of these debates construct a compelling research agenda for the political philosophy of internal displacement.
