Seal of the state of Indiana, USA

Indiana (/ˌɪndiˈænə/ IN-dee-AN-ə) is a state in the Midwestern region of the United States. It borders Lake Michigan to the northwest, Michigan to the north and northeast, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Nicknamed "the Hoosier State", Indiana is the 38th-largest by area and the 17th-most populous of the 50 states. Its capital and largest city is Indianapolis. Indiana was admitted to the Union as the 19th state on December 11, 1816. Indigenous resistance to American settlement was broken with their defeat in Battle of Tippecanoe in 1811, and the collapse of Tecumseh's confederacy in 1813. The new settlers were primarily Americans of British ancestry from the eastern seaboard and the Upland South, and Germans. After the Civil War, in which the state fought for the Union, natural gas attracted heavy industry and new European immigrants to its northern counties. In the first half of the 20th century, northern and central sections experienced a boom in goods manufacture and automobile production. Southern Indiana remained largely rural. After the rise and fall of the Klan in the 1920s, the state swung politically from the Republican to Democratic Party in the New Deal 1930s. Today, with a decades-long record of returning Republican majorities, Indiana is counted a "Red state". Indiana has a diverse economy with a gross state product in 2023 of 404.3 billion. Indianapolis is at the centre of the state's largest metropolitan area, with a population of over two million. The Fort Wayne metro area follows with a population of 645,000. The state's largest city, Indianapolis, is home to professional sports teams, including the NFL's Indianapolis Colts, the NBA's Indiana Pacers, and the WNBA's Indiana Fever. The city also hosts several notable competitive events, such as the Indianapolis 500, held at Indianapolis Motor Speedway.
