Washington County, Illinois: History
Washington County was formed on January 2, 1818, out of St. Clair County. It was named for George Washington. Despite its relative proximity to the Illinois suburbs of St. Louis, Missouri, the county is not considered part of the St. Louis metropolitan area, also known as the Metro-East. In 1813, the Lively Massacre occurred near Little Crooked Creek. In 1959, the state established the Washington County State Recreation Area. Washington County was initially settled by immigrants from Kentucky who moved northward out of that state in the early 1800s. In the late 1800s there were (relatively) large numbers of immigrants who settled in Washington County, and by the early 1900s there were large numbers of first-generation immigrants still living in Washington County. They primarily came from the four countries of Germany, Poland, Ireland and England.
