Globalization, climate change, and increased geopolitical competition are having a profound impact on the Arctic, affecting how we understand both sovereignty and security within the region. In Breaking Through, a diverse group of emerging and established scholars examine Arctic sovereignty and security, rarely examined together, and present a theoretically robust study of Arctic sovereignty and security in both historical and contemporary contexts. Throughout the volume, readers will discover fresh perspectives on under-studied dimensions of Arctic sovereignty, including: environmental changes, foreign and security policies, and how Indigenous peoples interact to produce different meanings of sovereignty and security in the Arctic. Drawing on extensive primary and secondary research, Breaking Through offers important and timely conclusions for policymakers, advocates, scholars, and students.
