This thesis investigates the relationship between space, place, and protest in London between 1780 and 2010, focussing primarily on four themes: communication and organisation; control of, and access to, public space; memory and commemoration; and repertoires of protest. Space, place, and protest are shown to be mutually constitutive, impacting and shaping each other in complex and interactive ways. The thesis demonstrates that although developments in areas such as communication technology and policing have impacted protest in the capital since 1780, some elements remain relatively unchanged: the ways in which protesters communicate and organise, despite new media; the ongoing struggle with the authorities for the highly symbolic public space of the capital; the ways in which collective memories of past protests are constructed and used; and the ways in which repertoires of protest develop. Combining a long-term historiographical approach with an event-based empirical focus, the thesis examines four case studies: the Gordon Riots (1780), the Hyde Park Railings Affair (1866), the Battle of Cable Street (1936), and the Student Tuition Fee Protest (2010). This thesis is primarily an exercise in historical geography, but it draws on, and contributes to, a range of scholarship in geography, history, and social science concerned with protest, social movements, London, and the urban.
