The attorney Abraham Lincoln occasionally had legal business in Jacksonville, frequently acting either as co-counsel or opposing counsel with David A. Smith, a Jacksonville resident. In what is now Central Park, Lincoln delivered a strong antislavery speech on September 6, 1856 in support of the presidential campaign of John C. Frémont, lasting over two hours. A mural depicting the event has been painted on the side of a building at the southwest corner of the square. During the antebellum years, Jacksonville was a stopping point on the historic Underground Railroad, as refugee slaves moved north to freedom, many going into Canada.
