The campaign of 1731 was a failed attempt by Tahmasp II of the Safavid dynasty to launch an offensive into Ottoman held Caucasus which ended in a disastrous defeat with all of Nader's gains during the previous year being lost. The result of this particular military catastrophe was still overturned with Nader's return from the east but would have much more significant impact on the Safavid dynasty itself as Tahmasp II sealed his own fate by initiating this ill fated expedition.
