The flag of Illinois

Illinois (/ˌɪlɪˈnɔɪ/ ⓘ IL-ih-NOY) is a state in the Midwestern United States. It borders on Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-most land area. Its capital city is Springfield in the center of the state, and the state's largest city is Chicago, located in northeastern Illinois.

Present-day Illinois was inhabited by Indigenous cultures for thousands of years. The French were the first Europeans to arrive, settling near the Mississippi and Illinois rivers in the 17th-century Illinois Country, as part of their sprawling colony of New France. A century later, the revolutionary war Illinois campaign prefigured American involvement in the region. Following U.S. independence in 1783, which made the Mississippi River the national boundary, American settlers began arriving from Kentucky via the Ohio River. Illinois was soon part of the United States' oldest territory, the Northwest Territory, and in 1818, it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany, Sweden, Hungary, and elsewhere.

In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network facilitated trade, commerce, and settlement, making the state a transportation hub for the nation, especially in Chicago, which became the world's fastest growing city by the late 19th century. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large black community, particularly in Chicago, which became a leading cultural, economic, and population center; the Chicago metropolitan area holds about 65% of the state's 12.8 million residents. Illinois, alongside Texas, is one of the most tornadically active states in the U.S; in 2023 alone, Illinois produced 136 tornadoes, the highest state by a significant margin.

USS Illinois in July 1945, just weeks before construction was canceled
USS Illinois in July 1945, just weeks before construction was canceled

USS Illinois (BB-65) was to be the fifth Iowa-class battleship constructed for the United States Navy and was the fourth ship to be named in honor of the 21st US state.

Hull BB-65 was originally to be the first ship of the Montana-class battleships, but changes during World War II resulted in her being reordered as an Iowa-class battleship. Adherence to the Iowa-class layout rather than the Montana-class layout allowed BB-65 to gain eight knots in speed, carry more 20 mm and 40 mm anti-aircraft guns, and transit the locks of the Panama Canal; however, the move away from the Montana-class layout left BB-65 with a reduction in the heavier armaments and without the additional armor that were to have been added to BB-65 during her time on the drawing board as USS Montana.

Like her sister ship Kentucky, Illinois was still under construction at the end of World War II. Her construction was canceled in August 1945, but her hull remained until 1958 when it was broken up. (Read more...)

1837 illustration of Black Hawk from History of the Indian Tribes of North America

Black Hawk, or Ma-ka-tai-me-she-kia-kiak in the Sauk language, (1767 – October 3, 1838) was a war leader of the Sauk American Indian tribe in what is now the Midwest of the United States. He earned his status as a war chief or captain by leading raiding and war parties as a young man, and a band of Sauk warriors during the Black Hawk War of 1832.

Black Hawk was born in 1767 in the village of Saukenuk on the Rock River (present-day Rock Island, Illinois). During the War of 1812, Black Hawk had fought on the side of the British against the U.S., hoping to push white American settlers away from Sauk territory. Later he led a band of Sauk and Fox warriors, known as the British Band, against European-American settlers in Illinois and present-day Wisconsin in the 1832 Black Hawk War. After the war, he was captured by U.S. forces and taken to the eastern United States. Shortly before being released from custody, Black Hawk told his story to an interpreter; aided also by a newspaper reporter, he published Autobiography of Ma-Ka-Tai-Me-She-Kia-Kiak, or Black Hawk, Embracing the Traditions of his Nation.... Black Hawk died in 1838 in what is now southeastern Iowa. He has been honored by an enduring legacy: his book, many eponyms, and other tributes. (Read more...)
