From bestselling author Simon Winchester, the extraordinary story of how America was united into a single nation. For more than two centuries, E pluribus unum - out of many, one - has been featured on America's official government seals and stamped on its currency. But how did America become `one nation, indivisible'? In this monumental history, Simon Winchester addresses this question, introducing the fearless trailblazers whose achievements forged and unified America. Winchester follows in the footsteps of America's most essential explorers, thinkers, and innovators. He treks vast swaths of territory, introducing these fascinating pioneers - some, such as Washington and Jefferson, Lewis and Clark being familiar, some forgotten, some hardly known - who played a pivotal role in creating today's United States. Throughout, he ponders whether the historic work of uniting the States has succeeded, and to what degree. `The Men Who United the States' is a fresh, lively, and erudite look at the way in which the most powerful nation on earth came together, from one of our most entertaining, probing, and insightful observers.
