The Battle of Yeghevard, also known as the Battle of Morad Tapeh, was the final major engagement of the Perso-Ottoman War of 1730–1735 where the principal Ottoman army in the Caucasus theatre under Koprulu Pasha's command was utterly destroyed by only the advance guard of Nader's army before the main Persian army could enter into the fray. The complete rout of Koprulu Pasha's forces led to a number of besieged Ottoman strongholds in the theatre surrendering as any hope of relief proved ephemeral in light of the crushing defeat at Yeghevard. One of Nader's most impressive battlefield victories, in which he decimated a force four or five times the size of his own, it helped establish his reputation as a military genius and stands alongside many of his other great triumphs such as at Karnal, Mihmandoost or Kirkuk.
