After escaping slavery on her own in 1849, Harriet Tubman helped others journey on the Underground Railroad. From 1850 to 1860 she made an estimated 13 trips and rescued around 70 enslaved people, including many members of her family. She also provided information so that others could find their way north to freedom. Tubman aided so many in escaping slavery that she was called "Moses."

Wanting to bring an end to slavery, Tubman also coordinated with abolitionists. During the Civil War, she became a nurse and a spy for the Union. And despite her ongoing financial struggles, she continued to fight for equality and justice by speaking out against prejudice and advocating women's suffrage. It's clear Tubman led a momentous life that made the world a better place.

c. 1822: Tubman is born as Araminta "Minty" Ross in Maryland's Dorchester County

Her parents, Ben Ross and Harriet "Rit" Green, are both enslaved, meaning Ross had the same status at birth.

Though her birthdate has often been listed as around 1820, a record from March 1822 lists that a midwife had been paid for tending to Green, which suggests the birth may have taken place in February or March of that year.

c. 1828: Tubman is about five or six years old when her enslavers hire her out to tend to an infant. She is whipped for any perceived mistakes.

c. 1834-36: An overseer throws a two-pound weight at another slave but hits Tubman's head. She barely survives the devastating injury and experiences headaches for the remainder of her life.
