Originally conceived by impresario Sergei Diaghilev, the Ballets Russes is widely regarded as the most influential ballet company of the 20th century, in part because it promoted ground-breaking artistic collaborations among young choreographers, composers, designers, and dancers, all at the forefront of their several fields. Diaghilev commissioned works from composers such as Igor Stravinsky, Claude Debussy, Sergei Prokofiev, Erik Satie, and Maurice Ravel, artists such as Vasily Kandinsky, Alexandre Benois, Pablo Picasso, and Henri Matisse, and costume designers Léon Bakst and Coco Chanel.
