Chicago is the largest city by population in the state of Illinois and the American Midwest, United States. It is a dominant center of finance, industry and culture in the region. The city, for much of its history, has been known informally as America's "Second City."
It is currently ranked as the third-most populous city in the United States after New York and Los Angeles, with a population of nearly 3 million people. The Chicago metropolitan area (commonly referred to as Chicagoland) has a population of over 9.7 million people in Illinois, Wisconsin and Indiana, making it also the third largest metropolitan area in the U.S.Adjacent to Lake Michigan, it is among the world's twenty-five largest urban areas by population, and rated an alpha world city by the World Cities Study Group at Loughborough University.
Often called The Windy City and The City of Broad Shoulders, Chicago was incorporated as a city in 1837 after initially being founded in 1833 near a portage between the Great Lakes and the Mississippi River watershed. The city soon became a major transportation hub in North America and quickly became the transportation, financial and industrial center of the Midwest. Today the city's attractions bring 44.2 million visitors annually.
Chicago was once the capital of the railroad industry and until the 1960s the world's largest meatpacking facilities were at the Union Stock Yards; currently the city is home to the nation's second busiest airport, O'Hare International.Chicago became notorious worldwide for its violent gangsters in the 1920s, most notably Al Capone, and for the political corruption in one of the longest lasting political machines in the nation. The city has long been a stronghold of the Democratic Party and has been home to numerous influential politicians including the current presidential nominee, Barack Obama
The name "Chicago" is the French rendering of the Miami-Illinois name shikaakwa, meaning “wild leek”. Etymologically, the sound /shikaakwa/ in Miami-Illinois literally means 'striped skunk', and was a reference to wild leek, or the smell of onions.The name was initially applied to the river, but later came to denote what is presently the site of the city. Louis Hennepin, a Catholic priest, missionary and explorer, first placed the name 'Chicago' on a map in 1683.
During the mid-18th century the area was inhabited primarily by Potawatomis, who had taken the place of the Miami and Sauk and Fox peoples. The first permanent settler in Chicago, Haitian Jean Baptiste Pointe du Sable, arrived in the 1770s, married a Potawatomi woman, and founded the area’s first trading post. In 1803 the United States Army built Fort Dearborn, which was destroyed in the 1812 Fort Dearborn massacre. The Ottawa, Ojibwa, and Potawatomi later ceded the land to the United States in the 1816 Treaty of St. Louis. On August 12, 1833, the Town of Chicago was organized with a population of 350. Within seven years it grew to a population of over 4,000. The City of Chicago was incorporated on March 4, 1837.
The city began its step toward regional primacy as an important transportation hub between the eastern and western United States. Begun in 1836, Chicago’s first railway, Galena and Chicago Union Railroad, opened in 1848, a year which also marked the opening of the Illinois and Michigan Canal. The canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River. A flourishing economy brought many new residents from rural communities as well as immigrants from abroad. The city’s manufacturing and retail sectors became dominant among Midwestern cities and subsequently influenced the American economy, particularly in meatpacking, with the advent of the refrigerated rail car and the regional centrality of the city's Union Stock Yards.
During its first century as a city, Chicago grew at a rate that ranked among the fastest growing in the world. Within the span of forty years, the city's population grew from slightly under 30,000 to over 1 million by 1890. By the close of the 19th century, Chicago was the fifth largest city in the world,and the largest of the cities that did not exist at the dawn of the century. Within fifty years of the Great Chicago Fire of 1871, the population had tripled to over 3 million.
In February 1856, the Chesbrough plan for the building of Chicago’s (and indeed the United States’) first comprehensive sewerage system was approved by the Common Council;a project that necessitated the physical raising of much of central Chicago to a new grade. Untreated sewage and industrial waste now flowed into the Chicago River, thence into Lake Michigan, polluting the primary source of fresh water for the city. The city responded by tunneling two miles (3 km) out into Lake Michigan to newly built water cribs. Nonetheless, spring rains continued to carry polluted water as far out as the water intakes. In 1900, the problem of sewage was largely resolved when Chicago undertook an innovative engineering feat. The city actually reversed the flow of the river, a process that started with the construction and improvement of the Illinois and Michigan Canal and completed with the finishing of the Chicago Sanitary and Ship Canal leading to the Illinois River which joins the Mississippi River.
After the Great Chicago Fire of 1871 destroyed a third of the city, including the entire central business district, Chicago experienced rapid rebuilding and growth. During Chicago's rebuilding period, the world's first skyscraper was constructed in 1885 using steel-skeleton construction.
In 1893, Chicago hosted the World's Columbian Exposition on former marshland at the present location of Jackson Park. The Exposition drew 27.5 million visitors, and is considered among the most influential world's fairs in history.The University of Chicago had been founded one year earlier in 1892 on the same South Side location. The term "midway" for a fair or carnival referred originally to the Midway Plaisance, a strip of park land that still runs through the University of Chicago campus and connects Washington and Jackson Parks.
The city was the site of labor conflicts and unrest during this period, which included the Haymarket affair on May 4, 1886. Concern for social problems among Chicago’s lower classes led Jane Addams to be a co-founder of Hull House in 1889. Programs developed there became a model for the new field of social work. The city also invested in many large, well-landscaped municipal parks, which also included public sanitation facilities.
The 1920s brought notoriety to Chicago as gangsters, including the notorious Al Capone, battled each other and law enforcement on the city streets during the Prohibition era. The 1920s also saw a major expansion in industry. The availability of jobs attracted African Americans from the South. Arriving in the tens of thousands during the Great Migration, the newcomers had an immense cultural impact. It was during this wave that Chicago became a center for jazz, with King Oliver leading the way.
In 1933, Mayor Anton Cermak was assassinated while in Miami with President Franklin D. Roosevelt.
On December 2, 1942, physicist Enrico Fermi conducted the world’s first controlled nuclear reaction at the University of Chicago as part of the top-secret Manhattan Project.
Mayor Richard J. Daley was elected in 1955, in the era of machine politics. Starting in the 1960s, many upper- and middle-class citizens started leaving the city for the suburbs, as was the case in many cities across the country. It took the heart out of many residential neighborhoods, leaving impoverished and disadvantaged citizens behind. Structural changes in industry caused heavy losses of jobs for lower skilled workers.
The city hosted the tumultuous 1968 Democratic National Convention, which featured physical confrontations both inside and outside the convention hall, including full-scale police riots in city streets. Major construction projects, including the Sears Tower (which in 1974 became the world’s tallest building), McCormick Place, and O'Hare Airport, were undertaken during Richard J. Daley's tenure. When he died, Michael Anthony Bilandic was mayor for three years. His loss in a primary election has been attributed to the city’s inability to properly plow city streets during a heavy snowstorm.
In 1979, Jane Byrne, the city’s first female mayor, was elected. She popularized the city as a movie location and tourist destination.
In 1983 Harold Washington became the first African American to be elected to the office of mayor, in one of the closest mayoral elections in Chicago. After Washington won the Democratic primary, racial motivations caused a few Democratic alderman and ward committeemen to back the Republican candidate Bernard Epton, who ran on the slogan Before it’s too late, a thinly veiled appeal to fear.[15] Washington’s term in office saw new attention given to poor and minority neighborhoods. His administration reduced the longtime dominance of city contracts and employment by ethnic whites.
Current mayor Richard M. Daley, son of the late Richard J. Daley, was first elected in 1989. He has led many progressive changes to the city, including improving parks; creating incentives for sustainable development, including green roofs; and major new developments. Since the 1990s, the city has undergone a revitalization in which some lower class neighborhoods have been transformed into pricey neighborhoods as new middle class residents have settled in the city.
Chicago is located in northeastern Illinois at the southwestern tip of Lake Michigan. It sits on the continental divide at the site of the Chicago Portage, connecting the Mississippi River and the Great Lakes watersheds. The city lies beside Lake Michigan, and two rivers — the Chicago River in downtown and the Calumet River in the industrial far South Side — flow entirely or partially through Chicago. The Chicago Sanitary and Ship Canal connects the Chicago River with the Des Plaines River, which runs to the west of the city.
When Chicago was founded in the 1830s, most of the early building began around the mouth of the Chicago River, as can be seen on a map of the city's original 58 blocks.
The overall grade of the city's central, built-up areas, is relatively consistent with the natural flatness of its overall natural geography, generally exhibiting only slight differentiation otherwise. The average land elevation is 579 feet (176 m) above sea level.
The lowest points are along the lake shore at 577 feet (176 m), while the highest point at 735 feet (224 m) is a landfill located in the Hegewisch community area on the city's far south side.
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 far south Lake Calumet Harbor. The Lake also moderates Chicago's climate, making it warmer in the winter and cooler in the summer.
Lake Shore Drive runs adjacent to a large portion of Chicago's lakefront. Parks along the lakeshore include Lincoln Park, Grant Park, Burnham Park and Jackson Park; 29 public beaches are found all along the shore. Near downtown, landfills extend into the Lake, providing space for the Jardine Water Purification Plant, Navy Pier, Northerly Island and the Museum Campus, Soldier Field, and large portions of the McCormick Place Convention Center. Most of the city's high-rise commercial and residential buildings can be found within a few blocks of the Lake.
"Chicagoland" is an informal name for the Chicago metro area, used primarily by copywriters, advertising agencies, and traffic reporters. There is no precise definition for the term "Chicagoland," but it generally means "around Chicago" or relatively local.
The Chicago Tribune, which coined the term, includes the city of Chicago, the rest of Cook County, eight nearby Illinois counties; Lake, McHenry, DuPage, Kane, Kendall, Grundy, Will and Kankakee, and two counties in Indiana; Lake and Porter.
The Illinois Department of Tourism defines Chicagoland as Cook County without the city of Chicago, and only Lake, DuPage, Kane and Will counties.The Chicagoland Chamber of Commerce defines it as all of Cook, and DuPage, Kane, Lake, McHenry and Will counties.
The Tribune's Robert R. McCormick defined Chicagoland as comprising everything in a 200-mile (320 km) radius in every direction (which would then include other larger cities such as Milwaukee, Rockford and Indianapolis) and reported on many different places within the area as being "local news."
Summers are warm & humid with average high temperatures of 80-84°F (27-29°C) and lows of 61-65 °F (16-19°C). Winters are cold, snowy and windy with temperatures below freezing. Spring and Fall are mild with low humidity. According to the National Weather Service, Chicago’s highest official temperature reading of 105 °F (41 °C) was recorded on July 17, 1995. The lowest temperature of −27 °F (−33 °C) was recorded on January 20, 1985.
Chicago’s yearly precipitation averages about 34 inches (860 millimeters). Summer is typically the rainiest season, with short-lived rainfall and thunderstorms more common than prolonged rainy periods.] Winter precipitation tends to be more snow than rain. Chicago's snowiest winter on record was that of 1929–30, with 114.2 inches (290 cm) of snow in total. Chicago’s highest one-day rainfall total was 6.63 inches (168.4mm) on September 13, 2008.The previous record of 6.49 inches (164 mm) had been set on August 14, 1987.
