A committee from New York purchased 17acres in Knox County in 1835, and the first 25 settlers arrived in 1836. They built temporary cabins in Log City near current Lake Storey, just north of Galesburg, having decided that no log cabins were to be built inside the town limits.Galesburg was home to the first anti-slavery society in Illinois, founded in 1837, and was a stop on the Underground Railroad. The city was the site of the fifth Lincoln-Douglas debate, on a temporary speaker's platform attached to Knox College's Old Main building on October 7, 1858. Knox College continues to maintain and use Old Main to this day. An Underground Railroad Museum and Lincoln-Douglas Debate Museum were built in Knox College's Alumni Hall after it had finished renovations.
