August 23 is International Day for the Remembrance of the Slave Trade and its Abolition. With blatant, nationwide attempts to keep truth-telling out of schools, it’s especially critical to teach the whole truth about American slavery. Use our Teaching Hard History framework, its accompanying online archives and databases, and this film to help you and your students dig deeper into lessons about the slave trade and its lasting effects, as well as an often-forgotten part of our nation’s history: Indigenous enslavement.
