America's Book shows how the Bible decisively shaped American national history even as that history influenced the use of Scripture. It explores the rise of a strongly Protestant Bible civilization in the early United States that was then fractured by debates over slavery, contested by growing numbers of non-Protestant Americans, and torn apart by the Civil War. This first comprehensive history of the Bible in America explains why Tom Paine's anti-biblical tract The Age of Reason (1794) precipitated such dramatic effects, how innovations in printing by the American Bible Society created the nation's publishing industry, why Nat Turner's slave rebellion of 1831 and the bitter election of 1844 marked turning points in the nation's engagement with Scripture, and why Theodore Roosevelt and Woodrow Wilson were so eager to commemorate the 300th anniversary of the King James Version of the Bible.
