For the first 28 years of her life, Harriet Tubman lived as a slave on a southern plantation. She saw the injustice of slavery and vowed one day to be a free person. Finally, with the help of a Quaker woman, she was able to escape to Philadelphia by way of the Underground Railroad. After her escape, Harriet began her quest to help free other slaves, and over a 10-year period, she led more than 300 people through the "Underground Railroad" to their freedom.
