The 1900s was a hodgepodge o culture coming together to form what we now call the USA. The end of WWI, WWII, and the Korean War saw a reshuffling of the global community. Traditional USA beliefs shifted away from Imperialism and Capitalism to the Great New Deal and Social Democracy. You could say, “Make America Great Again’ was a call back to pre-war ideas. But, honestly, the 1900s had no such significant era in time. There were prosperous times for a small portion of the population, but the community was struggling to hold it together. This accumulated in the marriage between Surrealism and Existentialism.
