In August 1914, World War I began and rapidly disrupted Paris’s avant‑garde art world. Cubism’s leading collaboration—Pablo Picasso and Georges Braque—was abruptly interrupted when Braque was mobilized into the French Army, while Picasso, a Spanish national, stayed in Paris and adjusted his work under wartime conditions.
Albert Gleizes was conscripted into military service in August 1914, but he continued to paint while in uniform. After his discharge in 1915, he left for New York City, helping shift some Cubist activity away from Paris as artists and ideas moved across borders during the war.
In December 1914, French authorities sequestered (legally seized) the inventory of the prominent Cubist dealer Daniel-Henry Kahnweiler, a German national living in exile. This weakened the prewar market network that had supported Cubist artists and pushed them to seek new patrons and dealers during and after the war.
Around late 1914 to 1915, Jean Metzinger produced Soldier at a Game of Chess, reflecting wartime experience without depicting battlefield violence directly. The work shows how Cubism continued during the conflict, but with subjects and themes shaped by mobilization and military life.
On May 11, 1915, Georges Braque was seriously wounded in the head at Neuville-Saint-Vaast and underwent emergency surgery. His injury and long recovery removed one of Cubism’s central innovators from painting for an extended period, deepening the movement’s wartime rupture.
Fernand Léger served at the front in the Argonne and made numerous sketches of modern warfare and soldiers. His wartime experience pushed him toward a more machine-like visual language, linking Cubist structure to the industrial look and feel of mechanized war.
In September 1916, Léger narrowly survived a mustard gas attack near Verdun and entered a period of convalescence. This interruption—common for many artist-soldiers—became a turning point, as trauma and recovery fed into new post-analytic (more simplified and solid) Cubist approaches.
By 1917, Braque was demobilized and resumed painting following his wartime injury. His return marked a partial revival of Cubism from within Paris, but under new circumstances: the prewar partnership with Picasso was over, and the movement’s direction had changed.
In 1917, Léger painted The Card Players (La Partie de cartes), portraying soldiers with rigid, mechanical forms. The picture connected Cubist fragmentation and simplification to the dehumanizing rhythms of wartime life, translating trench experience into a new, tougher visual style.
On May 18, 1917, the Ballets Russes production Parade premiered in Paris with sets and costumes designed by Picasso. The project showed Cubist ideas moving into performance and design, while Picasso’s own studio work increasingly mixed Cubist and more classical figure drawing during the war years.
In January 1918, dealer Léonce Rosenberg opened (and promoted) Galerie L’Effort Moderne in Paris, positioning it as a new center for Cubism during the final phase of the war. The gallery helped rebuild the market and public platform for Cubist artists after the disruption caused by mobilization and the loss of earlier dealer networks.
On November 11, 1918, the armistice took effect, ending fighting on the Western Front. For Cubism, the armistice did not “reset” the prewar scene; instead, it set the stage for a return under new leadership (notably dealers like Rosenberg) and new styles shaped by wartime absence, injury, and displacement.
In 1919, Rosenberg mounted a fast sequence of exhibitions featuring Cubist artists associated with his gallery, including figures such as Metzinger, Léger, Braque, Gris, and Picasso. These shows helped define a postwar “return” of Cubism—more organized, theory-driven, and tied to gallery promotion than the prewar, studio-centered moment.
On January 10, 1920, peace was ratified, ending the armistice period and confirming a new postwar order. By this point, Cubism had re-established itself institutionally through dealers and publications, but it had been transformed by the war’s disruptions—shifting from a pre-1914 breakthrough into a postwar movement with new priorities and competing modernist rivals.
