In December 1848, a young enslaved couple named Ellen and William Craft traveled openly by rail, coach and steamship from Macon, Georgia, to Philadelphia, Pennsylvania. Ellen, who passed for white, disguised herself as a wealthy disabled man, with William as "his" slave. When the new Fugitive Slave Law in 1850 put them at risk, they fled from the United States. Their very existence challenged the nation's core precepts of life, liberty, and justice for all.
