Caroline Quarlls was born into slavery in Missouri in 1826. When she was 16, her owner cut her hair in anger, which prompted Caroline to run away and become one of the first slaves to escape using the Underground Railroad. The Underground Railroad was a network of safe houses and routes that helped slaves travel north to free states or Canada, where slavery was illegal. Caroline's greatest accomplishment was reaching freedom in Canada, blazing the trail for many other runaway slaves who followed the Underground Railroad to freedom.
