In the spirit of Guns, Germs, and Steel, author and cultural historian Larry Len Peterson details the collision of European and Native American civilizations and the bloody aftermath that doomed a once-thriving people. Wide-ranging and brimming with fresh insights, American Trinity focuses on how the West was shaped by three implacable forces: Christian imperialism, Thomas Jefferson's Doctrine of Discovery, and George Armstrong Custer's hubris. As Peterson says, "History is important. When there is no knowledge of the past, there cannot be a vision of the future." Includes chapter endnotes, bibliography, and index.
