It grew quickly in the mid-19th century.[5] The Great Chicago Fire of 1871 destroyed many square miles and made more than 100,000 people homeless. Major efforts were made to rebuild it.[6] Chicago's population grew when more construction jobs came. By 1900, Chicago was the fifth-largest city in the world.[7] Chicago is known for its urban planning and zoning standards, for example, new construction styles from the Chicago School of architecture, the development of the City Beautiful Movement, and the steel-framed skyscraper.[8][9] Chicago built the first skyscraper in the world in 1885, the Home Insurance Building.

Richard M. Daley is the city's longest serving mayor

Jean Baptiste Point du Sable founded Chicago in the early 1700s. It was founded to create a canal to let boats on the Great Lakes to connect to the Mississippi River.[23][24] Later, the city became a trading center for food, crops, and fur. The city grew very fast because of how the river back then was clean and healthy to drink. In 1837, Chicago became a city. The city grew until the Great Chicago Fire in 1871. The fire lasted for almost a week. Almost half the city and its population were lost in the fire. After the fire, Chicago grew faster than ever.

Then, city's economy grew and more people migrated there from other parts of the world. many of the immigrants were Germans, Jews, Irish, Swedes, Poles, and Czechs. The immigrants were almost two-thirds of the city's population. In 1889, Jane Addams built Hull house in Chicago for children and the poor. In 1893, the city hosted the World's Columbian Exposition. In 1892, they created the University of Chicago.

In 1919, the city became known for its gangsters, for example Al Capone, Dean O’Banion, Bugs Moran, and Tony Accardo. In the 1929 Saint Valentine's Day Massacre, Al Capone ordered gangsters to be shot on St. Valentine's Day. Then, the city became known for John Dillinger, a bank robber. He could rob a bank in under two minutes. Dillinger was shot and killed at the Biograph Theatre in 1934.

Anton Cermak was the 44th mayor of Chicago. He was shot and killed during the Democratic party convention in 1933. A man tried to shoot Franklin D. Roosevelt and Cermak blocked the bullet to save the President. Cermak died hours later. In 1955, Mayor Richard J. Daley was a powerful and well known Democrat. He helped Martin Luther King and other activists share their thoughts without being arrested in Chicago.

The 1968 Democratic National Convention had large protests and riots outside the convention. Richard J. Daley helped create the construction sites for the Willis Tower, O'Hare International Airport, the McCormick Place, and the University of Illinois at Chicago. Jane Byrne helped Chicago to become one of the most popular tourist attractions in the United States. She was the first female mayor of Chicago.

In 1982, seven people were poisoned with cyanide in Tylenol pills across the city. This led to changes in the packaging of over-the-counter drugs and to federal anti-tampering laws.

In 1983, Harold Washington became the first African American mayor of Chicago. He helped clean all dangerous and poor neighborhoods in the city. He was later re-elected, but died of a heart attack. He would become the second mayor of Chicago to die from a heart attack while in office. The first was Richard J. Daley. Eugene Sawyer finished Washington's second full term. Sawyer was the second African American Mayor of Chicago.

In 1989, Richard M. Daley, the son of Richard J. Daley, became the mayor of Chicago. Daley was the longest serving Mayor of Chicago.

In 2011, Rahm Emanuel became the first Jewish Mayor of Chicago.

In 2012, the NATO Summit was held in Chicago and lasted for three days. The city would also host the 38th G8 summit. The G8 summit was moved to Camp David because Chicago already hosted the NATO summit.

Chicago has the fourth-largest gross domestic product (GDP) of any city in the world. It is behind Tokyo, New York City, and Los Angeles, and ahead of London and Paris.

In 2019, Lori Lightfoot was elected mayor, making Chicago the largest city to have a female, African-American, female, and LGBT+ mayor in the country.[25]

Chicago is known as the Windy City, but it is less windy than many other big American cities. Wind speeds range from 8 miles per hour (13 km/h) in late summer to 12 miles per hour (19 km/h) in spring months. The "Windy City" nickname could be connected to Chicago politicians from the 1800s.

Chicago is the county seat of Cook County. The government of the City of Chicago is divided into executive and legislative branches. Civil and criminal law cases are heard in the Cook County Circuit Court of the State of Illinois court system, or in the Northern District of Illinois, in the federal system. In the former, the public prosecutor is the Illinois State's Attorney, in the latter, the United States Attorney.

Mayors of Chicago[change | change source]

The Mayor of Chicago is the chief executive, elected by general election for a term of four years, with no term limits. The mayor appoints commissioners and other officials who oversee the various departments. In addition to the mayor, Chicago's two other citywide elected officials are the clerk and the treasurer. The City Council is the legislative branch and is made up of 50 aldermen, one elected from each ward in the city. The council enacts local ordinances and approves the city budget. Government priorities and activities are established in a budget ordinance usually adopted each November. The council takes official action through the passage of ordinances and resolutions.

The current mayor is Lori Lightfoot since 2019. Chicago is the largest city in the United States to have an African-American female and LGBT person as mayor.[45]

Transit systems[change | change source]

The Regional Transportation Authority (RTA) controls the function of the three service boards: CTA, Metra, and Pace.

  • The Chicago Transit Authority (CTA) controls public transportation in the city of Chicago. The CTA controls a large group of buses and a fast transit elevated and subway system known as the 'L' (for "elevated"), with lines shown by colors. Rapid transit lines go to Midway and O'Hare Airports. The CTA's rail lines have the Red Line, Blue Line, Green Line, Orange Line, Brown Line, Purple Line, Pink Line, and Yellow Line. The Red and Blue lines have 24‑hour service. That makes Chicago one of a handful of cities around the world to have rail service 24 hours a day. Another city with 24-hour service is New York City.
  • Metra, the nation's second-most used passenger regional rail network, operates an 11-line commuter rail service in Chicago and throughout the Chicago suburbs. The Metra Electric Line shares its trackage with Northern Indiana Commuter Transportation District's South Shore Line, which provides commuter service between South Bend and Chicago.
  • Pace provides bus and paratransit service in over 200 surrounding suburbs with some extensions into the city as well. A 2005 study found that one quarter of commuters used public transit.[50]

Greyhound Lines gives inter-city bus service to and from the city. Chicago is also the spot for the Midwest network of Megabus.

Amtrak long distance services come from Union Station. Chicago is one of the largest hubs of passenger rail service in the nation. The buses end in San Francisco, Washington, D.C., New York City, Indianapolis, New Oreleans, Portland, Seattle, Milwaukee, Quincy, St. Louis, Carbondale, Boston, Grand Rapids, Port Huron, Pontiac, Los Angeles, and San Antonio. They made an attempt in the early 20th century to connect Chicago with New York City via the Chicago – New York Electric Air Line Railroad. Parts of this were built, but it was never finished.
