Indiana
state of the United States of America

Indiana ( 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. The state's 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.
This brief starts where responsible research should: with the source description of “Indiana” as state of the United States of America. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as state of the United States of America. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q1415. VIAF identifies the subject as 129599983. The Library of Congress control number is n79022925. Authority coordinates are 39.933, -86.217. 2 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1816, 1811 and 1813.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
