Chicago

The name Chicago is derived from a French rendering of the indigenous Miami–Illinois word šikaakwa, which was a name for a wild relative of onion and garlic known to modern botanists as Allium tricoccum. The first known reference to the site of the city of Chicago as "Checagou" was by Robert de La Salle around 1679 in a memoir. Henri Joutel, in his journal of 1688, noted that the eponymous wild "garlic" grew profusely in the area. According to his diary of late September 1687: ... when we arrived at the said place called "Chicagou" which, according to what we were able to learn of it, has taken this name because of the quantity of garlic which grows in the forests in this region. The city has had several nicknames throughout its history, such as the Windy City, Chi-Town, Second City, and City of the Big Shoulders.

In the mid-18th century, the area was inhabited by the Potawatomi, an indigenous tribe who had succeeded the Miami, Sauk and Meskwaki peoples in this region. The first known permanent settler in Chicago was a trader, Jean Baptiste Point du Sable. Du Sable was of African descent, perhaps born in the French colony of Saint-Domingue (Haiti), and he established the settlement in the 1780s. He is commonly known as the "Founder of Chicago". In 1795, following the victory of the new United States in the Northwest Indian War, an area that was to be part of Chicago was turned over to the U.S. for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the U.S. Army constructed Fort Dearborn, which was destroyed during the War of 1812 in the Battle of Fort Dearborn by the Potawatomi before being later rebuilt. …

Chicago is located in northeastern Illinois on the southwestern shores of freshwater Lake Michigan. It is the principal city in the Chicago Metropolitan Area, situated in both the Midwestern United States and the Great Lakes region. The city rests on a continental divide at the site of the Chicago Portage, connecting the Mississippi River and the Great Lakes watersheds. In addition to it lying beside Lake Michigan, two rivers—the Chicago River in downtown and the Calumet River in the industrial far South Side—flow either entirely or partially through the city. Chicago's history and economy are closely tied to its proximity to Lake Michigan. While the Chicago River historically handled much of the region's waterborne cargo, today's huge lake freighters use the city's Lake Calumet Harbor on the South Side. …

The city's waterfront location and nightlife attracts residents and tourists alike. Over a third of the city population is concentrated in the lakefront neighborhoods from Rogers Park in the north to South Shore in the south. The city has many upscale dining establishments as well as many ethnic restaurant districts. These districts include the Mexican American neighborhoods, such as Pilsen along 18th street, and La Villita along 26th Street; the Puerto Rican enclave of Paseo Boricua in the Humboldt Park neighborhood; Greektown, along South Halsted Street, immediately west of downtown; Little Italy, along Taylor Street; Chinatown in Armour Square; Polish Patches in West Town; Little Seoul in Albany Park around Lawrence Avenue; Little Vietnam near Broadway in Uptown; and the Desi area, along Devon Avenue in West Ridge. …

Chicago has the third-largest gross metropolitan product in the United States—about $670.5 billion according to September 2017 estimates. The city has also been rated as having the most balanced economy in the United States, due to its high level of diversification. The Chicago metropolitan area has the third-largest science and engineering work force of any metropolitan area in the nation. Chicago was the base of commercial operations for industrialists John Crerar, John Whitfield Bunn, Richard Teller Crane, Marshall Field, John Farwell, Julius Rosenwald, and many other commercial visionaries who laid the foundation for Midwestern and global industry. Chicago is a major world financial center, with the second-largest central business district in the United States, following Midtown Manhattan. The city is the seat of the Federal Reserve Bank of Chicago, the Bank's Seventh District. …

During its first hundred years, Chicago was one of the fastest-growing cities in the world. When founded in 1833, fewer than 200 people had settled on what was then the American frontier. By the time of its first census, seven years later, the population had reached over 4,000. In the forty years from 1850 to 1890, the city's population grew from slightly under 30,000 to over 1 million. By the 1890 census, Chicago was the second most populous city in the United States. By 1900, it was the fifth largest in the world behind Berlin, Paris, New York, and London, and the largest city founded in the prior century. Within sixty years of the Great Chicago Fire of 1871, the population went from about 300,000 to over 3 million, and reached its highest ever recorded population of 3.6 million for the 1950 census. …
