Yankee na dvoru kralja Arthura

The protagonist, Hank Morgan, a mechanic from 19th-century Connecticut, mysteriously awakens in 6th-century England, at the court of King Arthur, after being hit in the head. Thanks to his knowledge of modern technology and practical sense, Hank quickly rises to the position of a powerful advisor, called "The Boss". Hank attempts to modernize medieval society by introducing technology (telegraph, bicycles, newspapers) and ideas of democracy, education and equality, mocking feudalism, church authority and chivalric customs. His exploits, such as using "spells" (scientific tricks) to outshine Merlin, bring him influence but also conflict with the church and nobility. The novel follows Hank's attempts at reform, his love affair with Alisande (Sandy), and his travels with Arthur, which expose the brutality and injustice of the Middle Ages. Twain uses satire to criticize not only medieval customs, but also contemporary social flaws, such as inequality, fanaticism and technological arrogance. The ending is tragic: Hank's reforms fail due to rebellion and church influence, and he returns to his own time, broken.
