Harriet Tubman was born in Maryland around 1820. At that time, slavery was legal in Maryland and many other states, mostly in the South. Tubman and her family were enslaved on a plantation. They were forced to pick crops and do other jobs.
Tubman escaped to Pennsylvania in 1849. To get there, she used what’s known as the Underground Railroad. It wasn’t a real railroad, but a series of secret routes. The routes led from the Southern states to the Northern states, where enslaved people could be free.
For enslaved people, the journey was full of danger. If found by slave catchers, they were returned to their owners and often punished. It was a risk Tubman was willing to take.
But once Tubman was free, she worried about the people she had left behind—and decided to rescue them. Over the next decade, she guided at least 70 other enslaved people to freedom, including much of her family. In 1863, Tubman helped lead a raid on several plantations in South Carolina, freeing hundreds more.
