Suleymanieh Palace: A Qajar era royal residence in Karaj

Fath Ali's reign saw increased diplomatic contacts with the West and the beginning of intense European diplomatic rivalries over Iran. His grandson Mohammad Shah, who fell under the influence of Russia and made two unsuccessful attempts to capture Herat, succeeded him in 1834. When Mohammad Shah died in 1848 the succession passed to his son Naser-e-Din, who proved to be the ablest and most successful of the Qajar sovereigns.
