Illinois actually became the 21st state on December 3, 1818. It was on April 18, 1818, that President James Monroe signed the statehood enabling act adopted by Congress which provided for a state Constitution and established our disputed northern boundary line, which made Winnebago County a part of Illinois rather than a part of Wisconsin.
