Chicago,the third biggest city in the USA
Chicago is the third most populous city in the United States, after New York City and Los Angeles. With 2.7 million residents, it is the most populous city in both the U.S. state of Illinois and the American Midwest. Its metropolitan area, sometimes called Chicagoland, is home to 9.5 million people and is the third-largest in the United States.The name "Chicago" is derived from a French rendering of the Native American word shikaakwa, translated as "wild onion" or "wild garlic", from the Miami-Illinois language.The first known reference to the site of the current city of Chicago as "Checagou" was by Robert de LaSalle around 1679 in a memoir written about the time.Henri Joutel, in his journal of 1688, noted that the wild garlic, called "chicagoua," grew abundantly in the area. During the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, who had taken the place of the Miami and Sauk and Fox peoples.The 1780s saw the arrival of the first known non-indigenous permanent settler in Chicago, Jean Baptiste Point du Sable, who was of African and European (French) descent.
In 1795, following the Northwest Indian War, an area that was to be part of Chicago was turned over to the United States for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the United States Army built Fort Dearborn, which was destroyed in the War of 1812, Battle of Fort Dearborn and later rebuilt.The Ottawa, Ojibwe, and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were eventually forcibly removed from their land following the Treaty of Chicago in 1833
