Chicago, city, United States: From the Early Days to 1850

Notable as dividing lines in the city are the two branches of the Chicago River. In early days the river was important because the narrow watershed between it and the Des Plaines River (draining into the Mississippi through the Illinois River) offered an easy portage that led explorers, fur traders, and missionaries from the Great Lakes to the Great Plains. Father Marquette and Louis Jolliet arrived here in 1673, and the spot was well known for a century before Jean Baptiste Point Sable (or Point DuSable or Point de Sable), a black man possibly of Haitian origin, set up a trading post at the mouth of the river. John Kinzie, who succeeded him as a trader, is usually called the father of Chicago.

A military post, Fort Dearborn, was established in 1803. In the War of 1812 its garrison perished in one of the most famous tragedies of Western history. Fort Dearborn was rebuilt in 1816, and the construction of the Erie Canal in the next decade speeded the settling of the Midwest and the growth of Chicago. Harbor improvements, lake traffic, and the peopling of the prairie farmlands brought prosperity to the city. The Illinois and Michigan Canal, however, authorized by Congress in 1827 and completed in 1848, was soon rendered virtually obsolete by the arrival of railroads.
