Final answer:
Harriet Tubman led over 300 slaves to freedom through the Underground Railroad, returning to the South multiple times to guide them, and became known as the Moses of her people.
Step-by-step explanation:
The woman who distinguished herself for her courageous efforts to lead more than 300 slaves to freedom through the Underground Railroad was Harriet Tubman. Born into slavery in Maryland around 1822, Tubman escaped in the late 1840s and returned to the South at least thirteen times to help other enslaved people, including her own family and friends, to escape slavery and seek liberty. Her deep commitment to Christianity fueled her resolve, and she became known as the Moses of her people for her role in guiding them to freedom, despite the perils posed by the Fugitive Slave Act of 1850.
