Chicago, Illinois, officially incorporated as a city in 1837, developed near a vital portage connecting the Great Lakes to the Mississippi River watershed. The city grew rapidly during the mid-19th century, and despite the devastating Great Chicago Fire of 1871—which destroyed several square miles and left over 100,000 people homeless—Chicago’s population and influence continued to expand. The city became a pioneer in urban planning and architecture, giving rise to the Chicago School, the City Beautiful movement, and the first steel-framed skyscrapers that defined modern city skylines.

Today, Chicago is an international center for finance, culture, commerce, industry, education, technology, telecommunications, and transportation. It hosts the world’s largest and most diverse derivatives market, accounting for 20% of global commodities and financial futures trading. O’Hare International Airport consistently ranks among the world’s busiest airports, while the region serves as a key railroad hub. In 2024, Chicago’s metropolitan economy generated over $919 billion in GDP, ranking sixth worldwide, with a workforce spread across multiple industries, none dominating more than 14% of employment.

Tourism thrives in Chicago, drawing 55 million visitors in 2024 to attractions like Lake Michigan beaches, iconic cultural institutions, and award-winning restaurants. The city has left an indelible mark on music, literature, theater, film, dance, and visual arts, with genres including jazz, blues, gospel, house, and hip-hop. Chicago is home to world-renowned institutions such as the Chicago Symphony Orchestra, the Lyric Opera of Chicago, and the Art Institute of Chicago, as well as top universities including the University of Chicago, Northwestern University, and the University of Illinois Chicago. Sports enthusiasts can enjoy professional teams in every major league, including two Major League Baseball franchises, and participate in events like the Chicago Marathon, one of the World Marathon Majors.
