In this paper we analyse past sociotechnical transitions, and based on that we discuss the prospects for the central state in promoting radical transitions towards improved sustainability today. The case studies include the sociotechnical systems in Sweden providing for: (a) urban housing; (b) passenger cars as a favoured mode of transport; and (c) piped water/wastewater, all fundamentally transformed over the first seven decades of the twentieth century and especially in the 1940s up until the 1960s. The core lesson from the case studies is that the central state, by taking an active role and by coordinating the roles of different stakeholders, values and knowledge as well as different policy areas and instruments, can accomplish a coherent and effective management of such transition processes. Also in contemporary network governance settings the central state is well suited to accomplish such an active and coordinative role based on its legitimate power to design and implement different public policy instruments.
