I want to know about American Realism and how is this period characterized?
American Realism is characterized by a focus on real life situations, people, dilemmas, and problems. It was a rejection of Romanticism, as well. Realism frequently dealt with moral and social crises, which were issues that Realists felt strongly about. In addition:
Although the realist aesthetic influenced European as well as American literature, the American tradition emerged somewhat later in the century and employed slightly different conventions than its continental counterpart. American Realism was most commonly a feature of narrative fiction, although authors occasionally applied its themes and literary techniques to poetry and drama as well. (eNotes)
