Filming Of Transformers 3', Chicago, United States

In 1803, the United States Army built Fort Dearborn, which was destroyed in the 1812 Battle of Fort Dearborn. The Ottawa, Ojibwe, and Potawatomi later ceded additional land to the United States in the 1804 Treaty of St. Louis. The Potawatomi were eventually forcibly removed from their land following the Treaty of Chicago in 1833. On August 12, 1833, the Town of Chicago was organized with a population of around 200. Within seven years it grew to a population of over 4,000. The City of Chicago was incorporated on March 4, 1837.
The name "Chicago" is a French rendering of the Native American word shikaakwa, meaning "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. The wild garlic plants, Allium tricoccum, were described by LaSalle's comrade, naturalist-diarist Henri Joutel, in his journal of LaSalle's last expedition.
