Answer:
American Romanticism was the first full-fledged literary movement that developed in the U.S.A. It was developed as a result of various literary, romantic movements in Europe. It was actually made up of a group of authors in the beginning who wrote and published between about 1820 and 1860, when the U.S. was still finding its feet as a new nation.
It was developed as reactions to the formal orthodoxy and Neoclassicism of the preceding period around 1818. It is a movement for the freedom from thee authority, forms, and conventions typical in Neoclassical literature of those times. It thus proposed and replaced the neoclassic emphasis which was based on reason, with its own emphasis based on imagination and emotions, while also replacing neoclassic emphasis on authority with its own emphasis on individuality, thus placing individual at the center of all life and things.
