What is the title of Mark Twain's 1892 novel about a claimant to the earldom of Rossmore?

Mark Twain’s 1892 novel about a claimant to the earldom of Rossmore is The American Claimant. The book follows American inventor and heir apparent Colonel Mulberry Sellers, whose connection to the British aristocracy creates a comic collision between republican ideals and inherited privilege.

The novel is set partly in the United States and partly in England, allowing Twain to satirize both American self-made ambition and the British class system. Its plot turns on mistaken identities, competing claims, and the contrast between people who possess titles and those who possess practical ability. Sellers is related to characters from Twain’s earlier novel The Gilded Age, though readers do not need to know that book to follow the story.

The title is sometimes confused with The Gilded Age because both novels involve wealth, social ambition, and political or aristocratic maneuvering. They are separate works: The Gilded Age appeared in 1873 and was co-written with Charles Dudley Warner, while The American Claimant was written by Twain alone and published in 1892.
