History of ballet
Ballet originated in the Renaissance court as an outgrowth of court pageantry in Italy, where aristocratic weddings were lavish celebrations. Tutus, ballet slippers and pointe work were not yet used. The choreography was adapted from court dance steps. Performers dressed in fashions of the times. For women that meant formal gowns that covered their legs to the ankle. Early ballet was participatory, with the audience joining the dance towards the end.
Paris Opera
In 1661 Louis XIV, who was a dancer himself and one of the great architects of baroque ballet (the art form which would one day evolve into classical ballet), established the Académie Royale de Danse, intended to codify court and character dances and to certify dance teachers by examination. From 1680 until Lully's death, it was under the direction of the great dancing master Pierre Beauchamp, the man who codified the five positions of the feet. When Lully took over the Opéra in 1672, he and Beauchamp made theatrical ballet an important part of the company's productions. The ballet of that time was merely an extension of the opera, having yet to evolve into an independent form of theatrical art. As it became more important, however, the dance component of the company began to be referred to as the Paris Opera Ballet. In 1713 an associated ballet school was opened, today known as the Paris Opera Ballet School. The Académie Royale de Danse remained separate, and with the fall of the monarchy in 1789 it disappeared.
