Ballet originated in the Italian Renaissance as entertainment for royalty during dinner. The first complete ballet work was "Le Ballet Comique de la Reine" in 1581 in Paris. The first professional ballet academy, the Académie Royale de Danse, was established by French King Louis XIV in 1661. In the 18th century, Marie Camargo and Marie Salle began shortening skirts and using flat shoes, helping ballet evolve dramatically and technically into the 19th century.
