Chicago emerged two decades after its Great Fire of 1871 to host America's second world's fair, and with it witnessed the birth of a Black cultural movement along with the city's general rebirth. First in the performing arts, then progressing slower in the visual and literary arts, the next four decades beheld the rise of the foundational elements of a Black Chicago Renaissance somewhat paralleling that in Harlem but in an asymmetrical fashion. While the tempo of aesthetic evolution through two distinct periods was imbalanced, overall progress appeared: with a transformation in the class structure, bringing necessary Black patronage to the forefront; an intelligentsia to spur interest and appreciation in the fine arts; and impressive, awe-inspiring creative production in painting, sculpture, photography and music.
