The 1908 bombardment of the Majlis of Iran (Persian: به توپ بستن مجلس) took place on 23 June 1908 in Tehran, during the Iranian Constitutional Revolution, when the Persian Cossack forces, commanded by Vladimir Liakhov and other Russian officers, bombarded and suppressed the Iranian parliament, the Majlis.
He enlisted the help of the Cossack Brigade to control the revolution, leaving the city of Tehran at their mercy.
[5][4] The loyalty of the Cossack Brigade was fully guaranteed, not only by the previous purge carried out by commander Vladimir Liakhov, but also by the king's distribution of a special bonus in 1908.
[6] Liakhov led the force in shelling the Majles and executing several leaders of the Constitutional Movement on June 23, 1908.
Liakhov was pardoned by the Constitutional leaders probably for the fear of a Russian attack and was sent back to Saint Petersburg, where he would be dismissed soon after to serve in the Caucasus campaign of the First World War.
