In this book I want to look at the connections between three dominant social trends: the growth of cities, the creation of a global society, and the con - struction of modernity. Urbanization, globalization, and modernization have received considerable attention but rarely are the connections and relations between them the subjects of similar attention. I want to focus on their inter - connectedness, the subtle as well as the surprising links between the three. I will develop ideas concerning what I have termed the Third Urban Revolution, the Late Modern Wave of Globalization and metropolitan modernities. Let us begin in this chapter with some definitions and provisional descriptions of the Third Urban Revolution.
