When World War II ended in 1945, America emerged as the only superpower. It had defeated Germany and Japan, it was the only nation with the bomb, and much of the rest of the world lay in ruins as a result of the war.

The United States seemed on the verge of its greatest age, and from that starting point, its people embarked on a journey through the next several decades of change. The Making of Modern America is the story of that journey.
