What were the major authors and works of the early 20th century?
I believe that some narrowing down of the topic would be very helpful for both you and the answers you will obtain to this question. For example, American Literature has its own “major authors and works” as opposed to British or French Literature. The origins of post- colonial literature would also emerge in this time period, as the starting of the movement began to take hold. Women authors as well as authors of color also began to start the process of emergence during the early 20th Century. I think that World War I played a rather big role in helping to shape the literature of the time period, which is why I would say poets such as Yeats could be seen as major forces of creation in the first half of the 20th Century, with works such as “The Second Coming” as an example of such prominence.
