Underground Railroad
Routes on the Underground Railroad led to free states, Canada, Mexico and overseas. While traveling along these routes, slaves received help from abolitionists and those who had sympathy to their cause. British North America was another popular stopping point. Slavery was not allowed there, and its long border gave many points of access. More than 30,000 people were said to have escaped there using the network at its best, although U.S. Census statistics shows only 6,000.
