John Brian Harley

J.B. Harley founded the discipline of critical cartography by arguing that maps are not objective, scientifically accurate representations of reality. Instead, he theorized that maps are social constructs that reflect and project the power dynamics, biases, and political agendas of their creators and patrons.

Harley's most influential work is his 1989 essay titled "Deconstructing the Map," published in the journal Cartographica. In this paper, he applied postmodern literary theory and Michel Foucault's concepts of power to the historical study of maps, fundamentally changing map theory.

Yes, Harley was a prominent historical geographer who co-edited the highly regarded multi-volume "History of Cartography" series alongside David Woodward. The first volume of this monumental academic series, published by the University of Chicago Press, focused on prehistoric, ancient, and medieval cartography.

Harley pointed out that maps exert power through the deliberate processes of selection and omission—meaning what is put on a map is just as important as what is left off. He argued that state-sponsored maps historically served as tools for territorial control, colonial expansion, and political propaganda.
