This volume examines the most spectacular struggle for democracy in post-handover Hong Kong. Bringing together scholars with different disciplinary focuses and comparative perspectives from mainland China, Taiwan and Macau, one common thread that stitches the chapters is the use of first-hand data collected through on-site fieldwork. This study unearths how trajectories can create favourable conditions for the spontaneous civil resistance despite the absence of political opportunities and surveys the dynamics through which the protestors, the regime and the wider public responses differently to the prolonged contentious space. The Umbrella Civil Resistance and Contentious Space in Hong Kong offers an informed analysis of the political future of Hong Kong and its relations with the authoritarian sovereignty as well as sheds light on the methodological challenges and promises in studying modern-day protests.
