Harriet Tubman was born into slavery but found her freedom traveling alone via the Underground Railroad. She would go on to free around 300 enslaved people in the years that followed. She began her work on the Underground Railroad by retrieving members of her own family, including her parents, several siblings and various nieces and nephews, according to biography.com. When the Civil War began, she supported the Union, working as a spy and a nurse before leading the daring Combahee Ferry Raid, which freed more than 700 enslaved people. Later in life. At last, she became a prominent voice in the abolitionist movement and also fought for voting rights for women, helping to shape a path from slavery and discrimination toward justice in the United States.
