The United States and Germany during the Twentieth Century presents a wide ranging comparison of American and German societies during the late 19th and 20th centuries. The two countries - the world's leading "rising powers" of the time - were both more similar and more different than is widely understood. Above all, their dual encounter with modernity brings out the richness of both societies as they faced unprecedented internal and external challenges, sometimes in isolation, but more often in combination or in parallel with one another.
