The document discusses fugitive slaves who escaped from their masters to gain freedom. Many fugitive slaves ran north to free states to escape slavery, while bounty hunters sought to capture them and return them south. The Underground Railroad helped slaves escape by providing secret routes and safe houses. The Fugitive Slave Act of 1850 required the return of all escaped slaves and increased efforts to capture fugitives. Notable fugitive slaves mentioned include Frederick Douglass, who escaped slavery twice and became a famous abolitionist speaker; Harriet Jacobs, who wrote of her experiences as a female slave; and John Thompson, about whom little is known besides his escape to Philadelphia and contribution to the abolitionist press.
