French court ballet reached its height under the reign of King Louis XIV. Louis founded the Académie Royale de Danse (Royal Dance Academy) in 1661 to establish standards and certify dance instructors. In 1672, Louis XIV made Jean-Baptiste Lully the director of the Académie Royale de Musique (Paris Opera) from which the first professional ballet company, the Paris Opera Ballet, arose. Pierre Beauchamp served as Lully's ballet-master. Together their partnership would drastically influence the development of ballet, as evidenced by the credit given to them for the creation of the five major positions of the feet. By 1681, the first "ballerinas" took the stage following years of training at the Académie.
