Today in discussion i was curious why Chicago was the designated city to hold the World's Fair.
Well... After some google searches i found the answer. It was written by Paul Barrett from the Illinois Institute of Technology
"For the business and civic leaders of Chicago, the World’s Columbian Exposition was the climactic event of a ritual by which the city “came of age.”  Chicago engaged in a long political struggle with New York and other Eastern cities for the right to hold the exposition: in the end, Chicago simply out-bid its rivals. Land and facilities were donated by business and the city, and most of the construction expenses were borne by local business."
