Washington Irving is the author tied to early American Romanticism and the Legend of Sleepy Hollow. He published The Sketch Book in 1819–20, which includes The Legend of Sleepy Hollow and Rip Van Winkle, blending folklore, humor, and a sense of American place to shape a distinctly national form of romance with a touch of the supernatural. Nathaniel Hawthorne is associated with dark romanticism and moral allegory, Edgar Allan Poe with Gothic and psychological horror, and Ralph Waldo Emerson with Transcendentalism. So Irving best fits the combination of early American romantic supernatural tales and Sleepy Hollow.

The Romantic Movement in American literature centers on imagination, emotion, nature, and the individual experience, reacting against the earlier emphasis on reason. In the United States, these ideas take hold in the early 19th century and flourish through the Civil War era, roughly 1800 to 1860. You can see it across genres: Washington Irving and James Fenimore Cooper helped build early American romantic narratives and wilderness themes; Poe explores Gothic and imaginative depths; Hawthorne and Melville probe moral complexity within Romantic sensibilities; Emerson and Thoreau articulate transcendentalist ideas that fuse spirit, nature, and social thinking; and Whitman’s poetry in the 1850s expands a democratic vision. This span captures the height and transition of Romantic ideas before Realism and Naturalism reshaped American literature in the latter half of the 19th century. The other time frames miss the full arc of Romantic influence or push beyond its traditional peak.

Postmodernism embraces self-referential techniques that call attention to the act of storytelling itself. Metafiction consciously blurs fiction and reality, intertextuality embeds references to other works within the text, and unreliable narrators undermine the assumed objectivity of narration. Together, these devices reflect postmodern playfulness and skepticism about universal meanings, making this term the best fit for a literary tendency built on those methods. Romanticism centers on intense emotion, individual imagination, and a reverence for nature, not the experimental storytelling methods described. Realism aims for faithful depiction of everyday life and social conditions, emphasizing verisimilitude rather than metafictional awareness. Naturalism extends realism with a focus on determinism and environmental forces shaping characters, rather than self-conscious narrative techniques.

In this period, public expression centers on portable print, spoken persuasion, and official records—the kinds of materials that circulated widely and shaped civic life. Pamphlets let writers argue a political point or critique social conditions quickly and cheaply, reaching readers across towns and colonies. Oratory—public speeches and powerful addresses—was the main way leaders, reformers, and preachers swayed large audiences, especially in political debates and religious revivals. Documents—charters, laws, proclamations, and foundational papers—captured authority, policy, and the facts of governance, giving legitimacy to movements and preserving history. Together these forms embody how people shared ideas, argued over public issues, and SAMPLErecorded decisions in a way that reached many, not just a private circle. By contrast, fiction like novels and plays, private letters and journals, or everyday catalogs tend to serve different purposes or audiences, and newspapers while important later, did not dominate as the primary channels of expression in the earlier period.
