The present study is an attempt to investigate Neoromanticism in American literature. Most references to the problem of Neoromanticism in this literature appear in Russian criticism, while in the history of American literature the term has not come to be imposed. Moreover, presenting the evolution of American literature from the turn of the nineteenth and twentieth centuries in American Literature. A Chronological Approach (1989), R. Carlsen attests only the existence of Realism and Naturalism. Another perspective is found in the preface to the Anthology of Modern American Poetry (1973) by M. Sterian. P. Comarnescu, the author of the preface, observes that in the nineteenth and twentieth centuries Romanticism formed and culminated. But, at the same time, other American poets, coming out of perceptual Naturalism, will seek a social Realism, [...], ―including in their creation the greatness and misery of the world; beauty and triviality; joys and sorrows; the ideal and the doubt; enthusiasm and irony; tenderness and humour ...‖. Also, ―in this broad Realism, Romanticism and noble aspirations, prophecy and satire, tenderness and irony do not disappear,‖ while the ―tone‖ is different. In a sense, P. Comarnescu noticed the continuity of the Romantic tradition, but he did not call it the Neoromantic phenomenon and attributed it to Social Realism. The existence of Neoromanticism was mentioned in Зарубежная литература XX века. 18711917 (1981). This study proposes, in fact, a conception that completes the above-mentioned points of view, and namely that at the end of the nineteenth century, in American literature is reported the ―battle‖ of Neoromanticism, New Aestheticism with Realism and Naturalism, and, among the specified ―isms‖, only Realism asserts itself at the turn of the century.
