The Underground Railroad provided fugitive slaves a means to escape from the South. Conductors like Harriet Tubman led runaways from the South, while antislavery Northerners helped by providing safe havens from slave catchers who roamed the Northern and border states searching for escapees. Most of the fugitives fled to Canada. The actual number of slaves assisted during the nearly 80 years that the network existed was not overwhelming, but the publicity generated served to fuel mistrust between the North and the South.
