Buddenbrooks (German: [ˈbʊdn̩ˌbʁoːks] ) is a 1901 novel by Thomas Mann, chronicling the decline of a wealthy north German merchant family over the course of four generations, incidentally portraying the manner of life and mores of the Hanseatic bourgeoisie in the years from 1835 to 1877. Mann drew deeply from the history of his own family, the Mann family of Lübeck, and their milieu. It was Mann's first novel, published when he was twenty-six years old. With the publication of the second edition in 1903, Buddenbrooks became a major literary success.
