A Connecticut Yankee in King Arthur's Court

In the book, a Yankee engineer from Connecticut named Hank Morgan receives a severe blow to the head and is somehow transported in time and space to England during the reign of King Arthur. After some initial confusion and his capture by one of Arthur's knights, Hank realizes that he is actually in the past, and he uses his knowledge to make people believe that he is a powerful magician. He attempts to modernize the past in order to make people's lives better, but in the end he is unable to prevent the death of Arthur. Twain wrote the book as a burlesque of Romantic notions of chivalry after being inspired by a dream in which he was a knight himself, severely inconvenienced by the weight and cumbersome nature of his armor.
