Connecticut Yankee in King Arthur’s court. Mark Twain. 1984.

Knocked unconscious, it is only when mechanic Hank Morgan comes to that he finds himself in 6th-century England rather than 19th-century America. Surrounded by the traditions and customs of Camelot and King Arthur’s court. Morgan dislikes the hereditary social class structure and state church and attempts to instil his American idealism and love for technology and progress in King Arthur’s people.
