Harriet Tubman (born Araminta Ross, c. 1820 – 10 March 1913) was an African-American abolitionist, humanitarian, and Union spy during the U.S. Civil War. After escaping from captivity, she made thirteen missions to rescue over seventy slaves 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.
