This chapter recounts that while the Potawatomi, Odawa, and Ojibwe were migrating into Illinois, the American colonists in the eastern reaches of North America were fighting for their national independence from the British. The war ended in 1783 with the victorious Americans founding a new nation. Four years later, the US government organized a swath of land that included parts of Illinois, Indiana, Ohio, Wisconsin, Minnesota, and Michigan into what is known as the Northwest Territory. Located within the boundary of this new jurisdiction was Starved Rock, which officially became part of the Northwest Territory in 1787. In 1823, the first Americans settled in the Starved Rock area. The chapter then looks at the Black Hawk War in 1832. The conflict began as a Sauk Indian response to American settlers moving onto lands ceded in 1804. Ultimately, treaties and land cession agreements written by representatives of the US government were intended to swindle the tribes; they denied basic due process rights to the Indians.
