Harriet Tubman was a remarkable African American woman who played a significant role in the history of the United States. Born into slavery around 1820 in Maryland, Tubman escaped to freedom in 1849. She then made multiple dangerous journeys back to the South to help other enslaved individuals escape through the Underground Railroad, a network of secret routes and safe houses.

Tubman became one of the most prominent conductors of the Underground Railroad, making about 13 missions and rescuing approximately 70 enslaved people, including family and friends. She earned the nickname "Moses" for her courage and leadership in guiding individuals to freedom.

During the Civil War, Tubman also served as a nurse, cook, and spy for the Union Army, and later became an advocate for women's suffrage. After the war, she continued to fight for civil rights, including working towards the rights of freedmen and women, and caring for the elderly.

Harriet Tubman's legacy as an abolitionist, humanitarian, and civil rights activist is celebrated and honored today. In 2016, she was selected to be the new face of the $20 bill, becoming the first African American woman to appear on U.S. currency.
