فتح علي شاه
In 1804, Russian general Pavel Tsitsianov attacked Erivan, but a "superior" Iranian army, under the command of crown prince Abbas Mirza, repelled the attack. In 1807, the central Iranian government of king Fath-Ali Shah Qajar (r. 1797-1834) appointed Hossein Khan Sardar as the new governor ("khan") of Erivan, and made him the commander-in-chief (hence, "sardar") of the Iranian forces to the north of the river Aras.
