This chapter outlines attempts by global cities scholars to explain historic networks. Research in global cities studies shows that we are living in an urban age, a high period for intercity relations that promises a reconsideration of history. Today’s world city network emerged in tandem with major shifts in the global economy, along with the gradual erosion of national borders in many spheres of politics. Global cities studies pose two major questions for cities today: First, how are cities shaping globalization? Second, how is globalization shaping lived experiences in cities? Global cities studies, led by John Friedmann, Saskia Sassen, Manuel Castells, and Peter J. Taylor presciently posed these questions in the midst of drastic contemporary changes in the architecture of the world economic system. The emphasis on late capitalism in world cities studies creates problems in the literature in need of challenge. This chapter stresses the need for a political history of city networks, identifying the absence of history of the literature as a flaw in need of change. Today’s world city network is far from a steady state or “end of history.”
