God Save the Tsar! was used until the February Revolution, when the Russian monarchy was overthrown. Upon the overthrow, in March 1917, the "Worker's Marseillaise" (), Pyotr Lavrov's modification of the French anthem "La Marseillaise", was used as an unofficial anthem by the Russian Provisional Government. The modifications Lavrov made to "La Marseillaise" included a change in meter from 2/2 to 4/4 and music harmonization to make it sound more Russian. It was used at governmental meetings, welcoming ceremonies for diplomats and state funerals.
