History

Ottawa occupies a place on the Illinois River that has long been one end of a portage trail between the Mississippi River and Lake Michigan. Here the river was reliably deep enough for canoes. The North Portage Trail connected the site over land and water to the Chicago River.

Ottawa was the site of the first of the Lincoln–Douglas debates on August 21, 1858. During the Ottawa debate, Stephen A. Douglas, leader of the Democratic Party, openly accused Abraham Lincoln of forming a secret bipartisan group of Congressmen to bring about the abolition of slavery.

The John Hossack House was a "station" on the Underground Railroad, and Ottawa was a major stop because of its rail, road, and river transportation. Citizens in the city were active within the abolitionist movement. Ottawa was the site of a famous 1859 extrication of a runaway slave named Jim Gray from a courthouse by prominent civic leaders of the time. Three of the civic leaders, John Hossack, Dr. Joseph Stout and James Stout, later stood trial in Chicago for violating the Fugitive Slave Act of 1850.
