At the decisive siege of Erivan of 1827, during the Russo–Persian War of 1826-1828, the Russian artillery gravely damaged the Sardar's Palace. After the Iranians were forced to cede Erivan to the Russians per the Treaty of Turkmenchay of 1828, the Erivan Sardar's palace was neglected by the Russians, and thus fell in ruins. A few decades later, in 1850, when Orientalism came in vogue, the Russians decided to rebuild the palace. The Russians commissioned Mirza Kadym Irevani to repaint the interior of the palace. Thus; "all historical figures depicted on the walls of the palace were from 30-40 years earlier than the time of Mirza Kadym Irevani".
