The Blaue Reiter (Blue Rider) was an influential art movement founded in 1911 in Munich, Germany. It was established by artists such as Wassily Kandinsky and Franz Marc, who sought to express spiritual truths through abstract forms and vibrant colors. The movement emphasized the emotional power of color and the importance of individual expression in art. The Blaue Reiter group organized exhibitions and published almanacs to promote their ideas. They believed that art should transcend the material world and connect with deeper, universal themes. This movement played a significant role in the development of modern art, influencing later styles like Abstract Expressionism.
