3. Harriet Tubman
Harriet Tubman, born into slavery in Maryland, escaped in 1849 and became a leading conductor on the Underground Railroad, guiding approximately 70 enslaved individuals to freedom. During the Civil War, she served as a scout and spy for the Union Army, notably leading the Combahee River Raid, which liberated over 700 enslaved people (history.com). Tubman’s unwavering courage and dedication have made her a lasting symbol of freedom and civil rights.
