"Grom pobedy, razdavaysya!" (Russian: Гром побе́ды, раздава́йся!; English translation: Let the thunder of victory sound) was an unofficial Russian national anthem in the late 18th and early 19th century.
The lyrics were written by the premier Russian poet of the time, Gavrila Derzhavin, and the music by composer Osip Kozlovsky, in 1791. The song was written to commemorate the capture of major Ottoman fortress Izmail by the great Russian general Aleksandr Suvorov. This event effectively ended the Seventh Russo-Turkish War.
The tune is a polonaise.
This anthem was eventually replaced by a formal imperial anthem, "God Save the Tsar!", which was adopted in 1833.
