Franz Marc
Wassily Kandinsky, Franz Marc, August Macke, Alexej von Jawlensky, Marianne von Werefkin, Gabriele Münter, Lyonel Feininger, Albert Bloch and others formed the group in response to the rejection of Kandinsky's painting "Composition V" from an exhibition. Der Blaue Reiter lacked an artistic manifesto, but it was centered on Kandinsky and Marc. Paul Klee was also involved.
