Charles Balesi, author of "The Time of the French in the Heart of North America, 1673-1818," will talk about the portion of Illinois which was once a part of the Louisina Territory – sold by Napoleon to the United State's during the Jefferson administration. Within this vast territory, only two areas saw substantial French settlement: Upper Louisiana (Haute-Louisiane), also known as the Illinois Country – which consisted of settlements in what are now the states of Missouri, Illinois and Indiana – and Lower Louisiana, which included parts of what became Louisiana, Arkansas, Mississippi and Alabama. Parts of "French Louisiana" became British when the French lost the French and Indian War in the middle of the 18th century. It then became U.S. territory after the success of the American Revolution; eventually designated as the Northwest Territory. The program, sponsored by Celebrate Woodstock, will be at the Woodstock Public Library, 414 W. Judd St. in Woodstock.
