The course examines the interplay between architecture and the built environment on the one hand and political belief ideas on the other. Our focus is on the twentieth century, sometimes dubbed an "age of ideologies." We will not assume that ideas are in uncomplicated ways reflected in architecture, nor that the descriptions architects give of their own work and intentions can be taken at face value. Students will become familiar with major architectural theories, different approaches in political theory, and also learn how to craft arguments at the intersection of politics and aesthetics.
