Les Hommes de bonne volonté () is an epic roman-fleuve by French writer Jules Romains, published in 27 volumes between 1932 and 1946. It has been classified both as a novel cycle and a novel and, at two million words and 7,892 pages, has been cited as one of the longest novels ever written. The volumes, written in chronological order from volume one, Le 6 octobre, through volume twenty-seven, Le 7 octobre, between them cover 6 October 1908 through 7 October 1933 in French life—an average of one volume per year, book-ended by one volume each for two particular days. The plot is expansive and features a large cast of characters, rather than narrowly focusing on individuals, but the two principals are Pierre Jallez, a poet loosely based on Romains, and Jean Jerphanion, a teacher who later goes into politics. They meet in volume 2 starting at the École Normale Supérieure and become friends. Jerphanion marries a woman named Odette and lives happily with her, while Jallez tries several times to find love and is eventually married to Françoise Mailleul. In the course of their careers, meanwhile, Jerphanion spends ten years in the Chamber of Deputies and is briefly Minister of Foreign Affairs, and Jallez finds success as a novelist, each trying to secure peace in their own way, though the First World War takes place halfway through the story, which ends with the first foreshadowings of World War II. Structurally, Men of Good Will is a roman-fleuve—a long work across several volumes with continuation of plot and related characters that may mean it forms a single novel. It has been described as a novel cycle or novel sequence, and as a novel, by different writers. Its full extent, at 2,000,000 words, across 7,892 pages, 779 chapters and 27 volumes, means it has been described as one of the longest novels ever written—sometimes the single longest. Men of Good Will and particularly certain portions of it—Encyclopædia Britannica picks out the victory parade at the end of World War I—are emblematic of Romain's philosophy of unanimism, characterised by an interest in the collective rather than individuals.
