History of LaSalle County

LaSalle County was formed on January 15, 1831, out of Tazewell and Putnam Counties. It is named for the early French explorer René-Robert Cavelier, Sieur de La Salle. La Salle was the first European recorded as entering the area. He traveled the Mississippi River upriver from the Gulf of Mexico, claimed the land for France, or rather as a possession of King Louis XIV, and named it Louisiana. In 1680, he and Henry de Tonty built Fort Crevecoeur on the Illinois River in present-day Tazewell County, and in 1683, they constructed Fort St. Louis on Starved Rock in present-day LaSalle County. By 1857, the county was served by the daily arrivals of two trains of the Illinois Central Railroad. As William D. Boyce reportedly founded the Boy Scouts of America in Ottawa, the council is named for him.
