Chicago is by Lake Michigan. Chicago became a city in 1837 and is in between the Great Lakes and the Mississippi River watershed. It grew quickly in the mid-19th century. The Great Chicago Fire of 1871 destroyed many square miles and made more than 100,000 people homeless. Major efforts were made to rebuild it. Chicago's population grew when more construction jobs came. By 1900, Chicago was the fifth-largest city in the world. Chicago is known for its urban planning and zoning standards, for example, new construction styles from the Chicago School of architecture, the development of the City Beautiful Movement, and the steel-framed skyscraper. Chicago built the first skyscraper in the world in 1885, the Home Insurance Building.
