Chicago was incorporated on March 4 in 1837.
Before becoming a city, the area known as Chicago was home to Native Americans- the Mascoutens and Miamis- who traded with neighboring tribes- the Potawatomis, Fox and Illinois. The word Chicago comes from the French version of the word shikaakwa, which means wild leek or skunk in the language of the Miama-Illinois. The wild leeks or onions grew along the Chicago River.
After the Black Hawk War in 1832, the tribes ceded Illinois lands in 1833.
