Illinois is known as the "Land of Lincoln," because it is where the 16th President spent his formative years. Chicago gained prominence as a canal port after 1848, and as a rail hub soon afterward. By 1857, Chicago was Illinois' largest city.
Illinois has three large geographical divisions. The first is Chicagoland, including the city of Chicago, its suburbs, and the adjoining exurban area into which the metropolois is expanding. This region even includes a few counties in Indiana and Wisconsin and by now streches halfway across the northern part of the state of Illinois toward the Iowa border.
Illinois' agricultural outputs are corn, soybeans, hogs, cattle, dairy products and wheat. Its industrial outputs are machinery, food processing, electrical equipment, chemical products, publishing, fabricated metal products, transportation equipment, petroleum and coal.
Other points of interest are the home of Mormon leader Joseph Smith in Nauvoo and, in Chicago: the Art Institute, Field Museum, Museum of Science and Industry, Shedd Aquarium, Adler Planetarium, Merchandise Mart, and Chicago Portage National Historic Site.
