The town grew at a rapid rate, and a town square was quickly developed. In 1829, the Presbyterian Reverend John M. Ellis worked to found a new "seminary of learning" in the new state of Illinois. A group of Congregational students at Yale College heard about his plans and headed westward to establish the new school. These students were a part of the famous "Yale Bands," groups of students who established several colleges in the frontier, what is now the Midwest. Illinois College was one of the first institutions of higher learning in the Midwest. A new courthouse was built on the square, churches were constructed, railroads were planned, and stores and taverns were built. By 1834, Jacksonville had the largest population of any city in the state of Illinois, vastly outnumbering Chicago (only founded the year before). In the 1830s, the town was on the path of Native Americans who were being forcibly removed by the federal government to west of the Mississippi. The Potawatomi passed through here in 1838 on what they called their Trail of Death as they were forced from their traditional homelands to the dry and barren Indian Territory to the west.
