The flag of Chicago consists of four red stars and two blue stripes on a white background. The stars represent events in the history of the city – the establishment of Fort Dearborn in 1803, the Chicago Fire in 1871, the World's Columbian Exposition in 1893, and the Century of Progress Exposition in 1933. The stripes represent the North and South branches of the Chicago River. The flag is very popular in the city, both for its bold design and as a sign of civic pride.
