The third most populous city in the United States, Chicago is home to over 2.7 million residents. First incorporated in 1837, Chicago is also a city with a long history. Early on, Chicago was originally home to many American tribes including the Potawatomi, the Miami, the Sauk, and the Fox. It was then a military post and then finally was settled.
