Slavery prohibition and the Underground Railroad

A map of various Underground Railroad routes.

The Northwest Ordinance region, comprising the heart of the Midwest, was the first large region of the United States that prohibited slavery (the Northeastern United States emancipated slaves in the 1830s). The regional southern boundary was the Ohio River, the border of freedom and slavery in American history and literature (see Uncle Tom's Cabin by Harriet Beecher Stowe and Beloved by Toni Morrison).
The Midwest, particularly Ohio, provided the primary routes for the Underground Railroad, whereby Midwesterners assisted slaves to freedom from their crossing of the Ohio River through their departure on Lake Erie to Canada. Created in the early 19th century, the Underground Railroad was at its height between 1850 and 1860. One estimate suggests that by 1850, 100,000 slaves had escaped via the Underground Railroad.^[44]
The Underground Railroad consisted of meeting points, secret routes, transportation, and safe houses and assistance provided by abolitionist sympathizers. Individuals were often organized in small, independent groups; this helped to maintain secrecy because individuals knew some connecting "stations" along the route, but knew few details of their immediate area. Escaped slaves would move north along the route from one way station to the next. Although the fugitives sometimes traveled on boat or train, they usually traveled on foot or by wagon.^[45]
The region was shaped by the relative absence of slavery (except for Missouri), pioneer settlement, education in one-room free public schools, democratic notions brought by American Revolutionary War veterans, Protestant faiths and experimentation, and agricultural wealth transported on the Ohio River riverboats, flatboats, canal boats, and railroads.^{[citation needed]}
