Mark Twain wrote across genres that blended sharp satire, regional realism, and social critique. His humorous fiction (The Adventures of Tom Sawyer, Huckleberry Finn) used colloquial dialogue and irony to expose societal hypocrisies, particularly racism and class divides. Travel literature (The Innocents Abroad, Roughing It) merged witty observation with cultural commentary, chronicling his global adventures. Historical fantasy (A Connecticut Yankee in King Arthur’s Court) employed time-travel satire to lampoon industrialization and imperialism. Twain also penned polemical essays (King Leopold’s Soliloquy), condemning colonialism and injustice, and speeches laced with his trademark wit. Across all genres, his work balanced irreverent humor with moral urgency, cementing his legacy as a chronicler of human folly and a pioneer of distinctly American storytelling.
