What were the social ramifications of World War 1?

Answer 1

One big ramification was that the U.S was considered a major world power on par with Britain and France after the war. The U.S had been "tried and tested" by this war, and it gained a lot of prestige through its participation and being on the winning side. Prior to this the U.S was considered something of a backwater, a country that wasn't as important in world affairs as Britain or other European powers. Before the war, the U.S was considered powerful but lacking the "muscle" to do what the British Empire could do.

World War 1 also marked the first time the U.S directly intervened in European affairs, helping to alter the European geopolitical landscape. Americans had never sent such large numbers of soldiers into foreign lands to die without having any direct national interest in what was going on.

In the period after the war women finally got the right to vote in the U.S, there was much illness(especially the flu) that went around the U.S and the world that was related to the war, killing thousands of people, along with an economic crisis. The crisis didn't last very long, it was over by the early 20s, and the U.S economy went through a dramatic growth period during the 1920s, which is why it is called "The Roaring 20s". This was a new era of unprecedented prosperity and optimism, which ended in the stock market crash of 1929 and the Great Depression shortly after.
