This period also saw the foundation of the Russian Musical Society (RMS) in 1859, led by composer-pianists Anton (1829–94) and Nikolay Rubinstein (1835–81). The Mighty Five was often presented as the Russian Music Society's rival, with the Five embracing their Russian national identity and the RMS being musically more conservative. However the RMS founded Russia's first Conservatories in St Petersburg and in Moscow: the former trained the great Russian composer Peter Ilyich Tchaikovsky (1840–93), best known for ballets like "Swan Lake", "Sleeping Beauty", and "The Nutcracker". He remains Russia's best-known composer outside Russia. Easily the most famous successor in his style is Sergey Rakhmaninov (1873–1943), who studied at the Moscow Conservatory (where Tchaikovsky himself taught).
