Thomas Mann’s novel Buddenbrooks: The Decline of a Family was first published in 1901 and came to be recognized as a monumental work in the canon of modern literature. Thomas Mann (1875­–1955) was a German novelist and recipient of the Nobel Prize in Literature in 1929 for his novels, Buddenbrooks and The Magic Mountain. Mann draws on his own family history to craft Buddenbrooks’ narrative, demonstrating profound understanding of societal and familial dynamics in the context of 19th-century Germany.

The novel falls within the genre of a family saga and charts the multi-generational story of the Buddenbrook family, focusing on themes such as societal decline, the burden of heritage, and the conflict between personal desire and family duty. While representative of the literary movement of realism, Mann’s work also includes early modernist motifs. Buddenbrooks reveals Mann’s understanding of German identity itself and his engagement with the philosophies of influential figures of the time such as Schopenhauer, Wagner, and Nietzsche.

Plot Summary

Part 1 of Buddenbrooks begins in 1835 with the Buddenbrook family settling into a new home in Lübeck, acquired through their successful trading firm. The patriarch, Johann Buddenbrook Senior, along with his son Johann Junior (Jean), who now leads the firm and serves as a consul, host a grand housewarming dinner. The event introduces various family members, including Jean’s wife Elisabeth and their children Antonie (Tony), Thomas (Tom), and Christian, as well as significant town figures.

Jean receives a letter from his estranged stepbrother, Gotthold, requesting his share of the inheritance. This introduces immediate tension since Gotthold’s marriage to a woman of lower social standing has alienated him from the family, complicating the inheritance issue.

In Part 2, Jean and Elisabeth celebrate their daughter Clara’s birthday. Tony’s summers at her grandparents’ villa contrast with her life in Lübeck, revealing her playful yet sometimes cruel nature influenced by family prejudices.

The differences between Jean’s sons—the business-minded Thomas and the unpredictable Christian—become evident. The deaths of Johann Buddenbrook and his wife Antoinette mark a significant transition as Jean assumes leadership of the family and reconciles with Gotthold. Thomas joins the family business, demonstrating maturity and dedication, while Tony’s unruly behavior leads her parents to enroll her in a boarding school where she forms close friendships with other girls from upper-class society.

Part 3 opens with the Buddenbrooks enjoying a summer day, during which Tony meets Bendix Grünlich, a man interested in marrying her. Despite her initial refusal, her parents pressure her to reconsider, citing Bendix’s suitability as a husband. Tony’s resistance to Grünlich is further tested during a vacation in Travemünde, where she forms a deep connection with Morten Schwarzkopf. Despite their mutual affection, the social and class divide between them makes the match undesirable in the eyes of her parents. When Tony receives a presumptuous letter from Grünlich, she confesses her love for Morten to her father, who insists on the importance of family duty over personal happiness. Tony returns to Lübeck, heartbroken, and eventually succumbs to familial pressure, recording her engagement to Grünlich in the family chronicle.

In Part 4, Tony adapts to married life in Hamburg. Political unrest in Lübeck leads to rising tension, including protests demanding liberal reforms. Meanwhile, Tony and Grünlich’s marriage deteriorates as Grünlich’s financial troubles become apparent. A visit from Tony’s father reveals the extent of Grünlich’s deceit in the marriage arrangement and his impending bankruptcy. Johann decides against bailing out Grünlich, leading to Tony’s return to Lübeck as a divorced woman with her daughter Erika. Soon after, Jean Buddenbrook dies suddenly.

Christian’s behavior continues to cause friction within the family, and he eventually leaves for Hamburg. Tony marries Permaneder, which she sees as a practical step. Once in Munich, she faces challenges adapting to her new life and is disappointed by Permaneder’s decision to retire early. She experiences a stillbirth. The marriage deteriorates, leading to Tony’s return to her family home after a scandalous incident involving Permaneder and their maid. The divorce is granted and Permaneder returns Tony’s dowry.

The firm’s 100th anniversary is marked by a disastrous telegram announcing the collapse of the Maiboom deal, a critical contract for the family business.
