Illinois, also known as the Land of Lincoln, was the twenty-first state to join the Union, when it was admitted on December 3, 1818. It lies in the eastern north-central United States and is surrounded by Wisconsin, Iowa, Missouri, Kentucky, Indiana, and Lake Michigan. Springfield is the state's capital, but Chicago is Illinois's most heavily populated city, with nearly three million residents.
