Answer:
Harriet Tubman was an African American abolitionist and humanitarian who played a crucial role in the Underground Railroad and the Civil War. Born into slavery in Maryland, she escaped in 1849 and subsequently made 13 missions to rescue approximately 70 enslaved people using the network of antislavery activists and safe houses known as the Underground Railroad. During the Civil War, she served as an armed scout and spy for the Union Army and helped to liberate more than 750 enslaved people. After the war, she was active in the movement for women's suffrage. Tubman's legacy continues to inspire and influence people today, as a powerful example of resistance against oppression and injustice.
