World War I was one of the milestones of a movement known as Modernism. That begins with the expectations of a group of minorities who insist on wanting to change the world and create a better world. Since then there have been technological developments that support their lives. But the emergence of new technologies was adding to a new problem for their country. Unemployment, crime and class disparity are becoming increasingly visible everywhere. These capitalist, industrialist, and nationalist practices and theories have greatly affected the ‘modern’ world. This also happened to the ‘western countries’ one of which is America. When we look back, when Puritans come to America, they have a picture that in this new place they will have peace in living the world, but in fact they still face many social problems that must be resolved. Not to mention they have to face political legitimacy, and must also be confronted with industrialized societies who monopolize their minds about how to distribute their wealth. The problems are increasingly complex in the modern era so it requires skill and thoughtful thinking to solve them. It is on this basis that American writers try to present the problems they find in a work, though it may not provide a solution but their works can be an important concern. Moreover, in the world of literature itself they have begun to be embarrassed by the previous streams of the flow of realism and naturalism. Modernists argue that the two schools are considered to have misused art as a medium to provide solutions to social problems, for the artist’s modernism is art. One of the hallmarks of the literature of this school is that its appreciation is more subjective, thus emphasizing the individual’s understanding, other than that the style of discussion tends to be complex. Notable figures of this era are Erza Pound with his famous works being Ripostes (1912), Hugh Selwyn Mauberley (1920), and The Cantos (1917-1969).

Melville (Moby-Dick), Hawthorne (Scarlet Letter) and Pose (The Hall of the House of Usher) these three figures are popular literary works of this time. American 19th century poetry has a different style, as for 2 writers: Walt Whitman (1819-1892) he is a nurse and innovator and his work is always about the American experience and he himself as a figure involved in the work.
