Book excerpt: "What to the slave is the Fourth of July?," asked Frederick Douglass in 1852. In Enjoy the Same Liberty, Edward Countryman addresses Douglass's question. He shows how the American Revolution began the world-wide destruction of slavery, how black Americans who seized their chances for freedom during the Revolution changed both themselves and their epoch, and how their heirs, including Douglass, pondered what the Revolution meant for them. Thanks in good part to black people, what began as colonial tax protests became something of far greater significance. But this book also shows how that same Revolution led to an immensely powerful slave society in the South, so strong that destroying it required the cataclysm of the Civil War.
