Scholarly literature on "global cities" has been criticized for ignoring the long-term historical context within which cities articulate the relationship between the global and the local. Employing a longue durée globalization perspective, this paper historicizes the unequal and uneven nature of contemporary urban development in Mumbai, India's "global city." The paper uses two analytical frames: the "port city" and the "colonial city" to highlight two essential dimensions of Mumbai's contemporary transformation of interconnectedness and segmentation based on unequal power.
