Blue Rider. Der Blaue Reiter is a designation by Vassily Kandinsky and Franz Marc for their exhibition and publication activities, in which both artists acted as sole editors in the almanac of the same name, first published in mid-May 1912. The editorial team organized two exhibitions in Munich in 1911 and 1912 to demonstrate their art-theoretical ideas based on the works of art exhibited. Travelling exhibitions in German and other European cities followed. The Blue Rider disbanded at the start of World War I in 1914. The artists associated with Der Blaue Reiter were important pioneers of modern art of the 20th century; they formed a loose network of relationships, but not an art group in the narrower sense like Die Brücke in Dresden. The work of the affiliated artists is assigned to German Expressionism. The forerunner of The Blue Rider was the Neue Künstlervereinigung München, instigated by Marianne von Werefkin, Alexej von Jawlensky, Adolf Erbslöh and the German entrepreneur, art collector, aviation pioneer and musician Oscar Wittenstein. The N.K.V.M was co-founded in 1909, and Kandinsky, as its first chairman, organized the exhibitions of 1909 and 1910. Even before the first exhibition, Kandinsky introduced the so-called four square meter clause into the statutes of the N.K.V.M due to a difference of opinion with the painter Charles Johann Palmié, this clause would give Kandinsky the lever to leave the N.K.V.M in 1911. In 1911, Palmié allowed Kandinsky and Marc to leave the association and organize the first Blue Rider exhibition. The Blue Rider was thus a spin-off from the N.K.V.M. When there were repeated disputes among the conservative forces in the N.K.V.M, which flared up due to Kandinsky's increasingly abstract painting, he resigned the chairmanship on 10 January 1911 but remained in the association as a simple member. His successor was Adolf Erbslöh. In June, Kandinsky developed plans for his activities outside of the N.K.V.M. He intended to publish a kind of almanac which could be called Die Kette. On 19 June, he pitched his idea to Marc and won him over by offering him the co-editing of the book. The name of the movement is the title of a painting that Kandinsky created in 1903, but it is unclear whether it is the origin of the name of the movement, as Professor Klaus Lankheit learned that the title of the painting had been overwritten. Kandinsky wrote 20 years later that the name is derived from Marc's enthusiasm for horses and Kandinsky's love of riders, combined with a shared love of the colour blue. For Kandinsky, blue is the colour of spirituality: the darker the blue, the more it awakens human desire for the eternal. Within the group, artistic approaches and aims varied from artist to artist; however, the artists shared a common desire to express spiritual truths through their art. They believed in the promotion of modern art; the connection between visual art and music; the spiritual and symbolic associations of colour; and a spontaneous, intuitive approach to painting. Members were interested in European medieval art and primitivism, as well as the contemporary, non-figurative art scene in France. As a result of their encounters with cubist, fauvist and Rayonist ideas, they moved towards abstraction. Der Blaue Reiter organized exhibitions in 1911 and 1912 that toured Germany. They also published an almanac featuring contemporary, primitive and folk art, along with children's paintings. In 1913 they exhibited in the first German Herbstsalon. The group was disrupted by the outbreak of the First World War in 1914. Franz Marc and August Macke were killed in combat. Wassily Kandinsky returned to Russia, and Marianne von Werefkin and Alexej von Jawlensky fled to Switzerland. There were also differences in opinion within the group. As a result, Der Blaue Reiter was short-lived, lasting for only three years from 1911 to 1914. Supported by their dealer Galka Scheyer, Kandinsky, Feininger, Klee and Alexej von Jawlensky formed Die Blaue Vier group in 1923. Together they exhibited and lectured in the United States from 1924. An extensive collection of paintings by Der Blaue Reiter is exhibited in the Städtische Galerie in the Lenbachhaus in Munich. Conceived in June 1911, Der Blaue Reiter Almanach was published in early 1912, by Piper, Munich, in an edition of 1100 copies; on 11 May, Franz Marc received the first print. The volume was edited by Kandinsky and Marc; its costs were underwritten by the industrialist and art collector Bernhard Koehler, a relative of Macke. It contained reproductions of more than 140 artworks, and 14 major articles. A second volume was planned, but the start of World War I prevented it. Instead, a second edition of the original was printed in 1914, again by Piper.
