This thesis explores the ways in which civil and uncivil groups in Northern Ireland use the Internet to generate soft power. This research assesses whether the Internet creates a critical multiplier effect for marginal groups, such as terrorists and interface communities. A coding scheme, adapted from previous studies of political part websites, is used to determine whether these groups have realised the potential of the Internet as a tool for political mobilisation. The dissertation considers whether there are any qualitative differences between the online framing of terrorist-linked parties and the constitutional parties in the region.
