Book excerpt: Fleeing repression and persecution, nearly five hundred French-speaking anarchists moved to London between 1880 and 1914, where they developed a unique community deeply shaped by political exile and activism. In this book Constance Bantman explores the history of these largely unknown people and the ways they reinvented anarchism at a time of tremendous political change. She looks at how they struggled in the massive late-Victorian metropolis, tracing their social and political interactions and examining the effects British and French surveillance had on their lives. An in-depth look at a fascinating community, The French Anarchists in London lends historical insight into contemporary concerns about transnational terrorist groups and immigration in Europe.
