Final answer:
Harriet Tubman made thirteen trips to the South as a conductor of the Underground Railroad, personally liberating approximately seventy enslaved individuals and assisting over three hundred in their quest for freedom.
Step-by-step explanation:
Harriet Tubman, a renowned abolitionist and conductor of the Underground Railroad, is credited with making thirteen trips to the South to rescue enslaved individuals, leading them to freedom in the North. She was born enslaved in Maryland and escaped in 1849, subsequently becoming a key figure in the abolition movement. Tubman helped approximately seventy enslaved people, including her family members, escape to freedom, sometimes referred to as her 'own people.' In a broader context, she aided over three hundred freedom-seekers throughout her involvement with the Underground Railroad. Tubman's contributions to the fight against slavery and the liberation of her fellow enslaved African Americans have solidified her legacy as an American hero, likened to figures such as Joan of Arc and Florence Nightingale for her heroism.
