Book excerpt: From the turn of the twentieth century until the end of the Irish Civil War, Protestant nationalists forged a distinct counterculture within an increasingly Catholic nationalist movement. Drawing on a wide range of primary and secondary sources, Conor Morrissey charts the development of nationalism within Protestantism, and describes the ultimate failure of this tradition. The book traces the re-emergence of Protestant nationalist activism in the literary and language movements of the 1890s, before reconstructing their distinctive forms of organisation in the following decades. Morrissey shows how Protestants, mindful of their minority status, formed interlinked networks of activists, and developed a vibrant associational culture. He describes how the increasingly Catholic nature of nationalism - particularly following the Easter Rising - prompted Protestants to adopt a variety of strategies to ensure their voices were still heard. Ultimately, this ambitious and wide-ranging book explores the relationship between religious denomination and political allegiance, casting fresh light on an often-misunderstood period.
