formed. Both the classes and the school quickly became popular. As surprising as the number of students who enrolled was their extreme diversity. Bureaucrats, merchants, tradesmen and university students attended, as well as many young women who lacked the means to study privately. In 1860, helped and encouraged by his brother Anton, Nikolai Rubinstein and Prince Nikolai Petrovitch Troubetzkoy founded a Moscow branch of the RMS in Rubinstein's own house. This branch proved so successful that they eventually relocated it into larger quarters and expanded their work there. Troubetzkoy was the chairman of RMS for seventeen years. The RMS's formal successors were the St. Petersburg Conservatory, which opened (also under the auspices of Anton Rubinstein), in September 1862, and the Moscow Conservatory, founded by Nikolai Rubinstein and Prince Nikolai Petrovitch Troubetzkoy in September 1866. Disbandment and revival Following the Russian Revolution of 1917, the RMS was disbanded in the same year. The All-Russian Musical Society, which was established in 1987 is meant to be the legal successor of the Russian Musical Society traditions and cultural legacy. On February 18 of 2010 upon the decision of the All-Russian Music Society Fifth convention the society was renamed back to the original title of the Russian Music Society, which marked the official reincarnation of the original organization. The modern RMS is the public agency with functions of the creative union. It consolidates thousands of people that represent musical and choreographic culture of Russia and its nations on both professional and amateur levels. The Society has chapters in all Russian regions, which allows it to effectively influence the condition and development of the modern musical and choreographic art in the country, as well to track and analyze cultural trends. Among major forms of the RMS involvement and its regional branches are organization of concerts, folklore holidays, master classes, music festivals and competitions. The RMS also assists Russian soloists and music groups in participation at the International festivals, competitions and concert tours.
