Book excerpt: Late-Victorian London was home to many exiled anarchist groups who fled persecution in their home countries. In this book Pietro Di Paola looks at the lives of Italian anarchists, balancing an examination of their political organizations and activities with a study of their everyday lives as exiles and militants. Central to the book is an analysis of the processes by which the Italian anarchists created an international revolutionary network, what would be seen as an extremely dangerous threat by European and American governments. By investigating the political, social, and cultural aspects of this radical Italian group, The Knights Errant of Anarchy speaks to political radicalism within immigrant communities at large.
