This article considers the use of the Internet by Irish Republicans and does so by applying thematic content analysis to a sample of websites that support the Irish Republican movement. Particular attention is paid to the Irish Republican virtual community which, through regular user interaction, creates and sustains an online discourse of support for their cause and the currently active dissident movements. Further analysis focuses on the function of a virtual community and the interactions facilitated by this online social space in relation to the potential for increased commitment to, and involvement in, support-related activities both on and off line.
