Der Blaue Reiter
Der Blaue Reiter (The Blue Rider) was a group of artists united in rejection of the Neue Künstlervereinigung München in Munich, Germany, which the group thought had become too strict and traditional. The group was founded by a number of Russian emigrants, including Wassily Kandinsky, Alexej von Jawlensky, Marianne von Werefkin, and native German artists, such as Franz Marc, August Macke and Gabriele Münter.
Der Blaue Reiter lasted from 1911 to the outbreak of WWI in 1914.
