Ottawa was the site of the first of the Lincoln-Douglas debates of 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.

Three of the civic leaders, John Hossack, Dr. Joseph Stout and James Stout, later stood trial in Chicago for violating the Fugitive Slave Law of 1850.
