Over the past six or more decades, John Friedmann has been an insurgent force in the field of urban and regional planning, transforming it from its traditional state-centered concern for establishing social and spatial order into a radical domain of collaborative action between state and civil society for creating 'the good society' in the present and future. By opening it up to theoretical engagement with a wide range of disciplines, Friedmann's contributions have revolutionised planning as a transdisciplinary space of critical thinking, social learning, and reflective practice.

Insurgencies and Revolutions brings together former students, close research associates, and colleagues of John Friedmann to reflect on his contributions to planning theory and practice. The volume is organized around five broad themes where Friedmann's contributions have risen to challenge established paradigms and generated the space for revolutionary thinking and action in urban and regional planning – Theorising hope; Economic development and regionalism; World cities and the Good city; Social learning, empowered communities, and citizenship; and Chinese cities. The essays by the authors reflect their engagement with his ideas and the new directions in which they have taken these in their work in planning theory and practice.
