Insurgent Communities is an absolute must-read. Through the meticulous examination of Filipino migrant activism in the US and The Netherlands, Quinsaat effectively demonstrates how contentious politics forge diaspora movements. Her impressive fieldwork, interviews, and archival research effectively illustrate how episodes of contention reconfigure migrants’ sense of their ‘imagined’ communities, identities, and corresponding solidarities. Using rich accounts that highlight the lived experiences of Filipino activists, she shows how these episodes motivate migrants to act collectively to increase their rights and political influence, both at home and abroad. By shedding light on how diasporas are constructed and become effective forces for change, Quinsaat’s book makes an outstanding contribution to the study of social movements, culture, migration, and transnational sociology.
