Harriet Tubman (born Araminta Harriet Ross; 1820 – March 10, 1913) was an African-American abolitionist, humanitarian, and Union spy during the American Civil War. After escaping from slavery, into which she was born, she made thirteen missions to rescue more than 70 slaves^[1] using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped John Brown recruit men for his raid on Harpers Ferry, and in the post-war era struggled for women's suffrage.

As a child in Dorchester County, Maryland, Tubman was beaten by masters to whom she was hired out. Early in her life, she suffered a head wound when hit by a heavy metal weight. The injury caused disabling seizures, narcoleptic attacks, headaches, and powerful visionary and dream activity, which occurred throughout her life. A devout Christian, Tubman ascribed the visions and vivid dreams to revelations from God.
