Race, Slavery, Freedom

Before the Battle of Gettysburg, Pennsylvania was a battleground of another sort.  For 85 years, African-American freedom seekers fled from Maryland into southern Pennsylvania, often pursued by sinister slavecatchers.  Simultaneously, a nationwide discussion was raging over what it meant to be an American.  Lessons explore these discussions and bring a human perspective to the debates over slavery.
