Why does ballet become the quintessence of Russia?

In Russia, a very famous czar strongly advocated social activities, encouraged theatrical performances and dances, and used dance as a means to break conservative customs. Under his advocacy, Russian nobles applied for dance teachers from abroad to learn western European dance. By the end of Peter the Great's reign, the Russian aristocratic society had completely mastered the dance in Europe. With the development of Russian industrialization, Russia urgently needs to train a group of talents who are familiar with western European culture, politics and military affairs. "Westernization" or "Frenchization" has become Russia's improved national policy for many years. Under such circumstances, ballet, as a symbol of advanced civilization, has been respected from top to bottom.
