Chicago ( (listen) shih-KAH-goh, locally also shih-KAW-goh), officially the City of Chicago, is the most populous city in the U.S. state of Illinois, and the third-most-populous city in the United States. With an estimated population of 2,693,976 in 2019, it is also the most populous city in the Midwestern United States. Chicago is the county seat of Cook County, the second-most-populous county in the US, with a small portion of the northwest side of the city extending into DuPage County near O'Hare Airport. Chicago is the principal city of the Chicago metropolitan area, often referred to as Chicagoland. At nearly 10 million people, the metropolitan area is the third most populous in the United States.
Located on the shores of freshwater Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed and grew rapidly in the mid-19th century. After the Great Chicago Fire of 1871, which destroyed several square miles and left more than 100,000 homeless, the city made a concerted effort to rebuild. The construction boom accelerated population growth throughout the following decades, and by 1900, less than 30 years after the great fire, Chicago was the fifth-largest city in the world. Chicago made noted contributions to urban planning and zoning standards, including new construction styles (including the Chicago School of architecture), the development of the City Beautiful Movement, and the steel-framed skyscraper.Chicago is an international hub for finance, culture, commerce, industry, education, technology, telecommunications, and transportation. It is the site of the creation of the first standardized futures contracts, issued by the Chicago Board of Trade, which today is part of the largest and most diverse derivatives market in the world, generating 20% of all volume in commodities and financial futures alone.

Luanda (), is the capital and largest city in Angola. It is Angola's primary port, and its major industrial, cultural and urban centre. Located on Angola's northern Atlantic coast, Luanda is Angola's administrative centre, its chief seaport, and also the capital of the Luanda Province. Luanda and its metropolitan area is the most populous Portuguese-speaking capital city in the world, with over 8.3 million inhabitants in 2020 (a third of Angola's population).
Among the oldest colonial cities of Africa, it was founded in January 1576 as São Paulo da Assunção de Loanda by Portuguese explorer Paulo Dias de Novais. The city served as the centre of the slave trade to Brazil before its prohibition. At the start of the Angolan Civil War in 1975, most of the white Portuguese left as refugees, principally for Portugal. Luanda's population increased greatly from refugees fleeing the war, but its infrastructure was inadequate to handle the increase.
