Nader Shah
In early 1744 Nader Shah resumed his offensive and besieged Kars, but returned to Dagestan to suppress a revolt. He returned afterwards and routed an Ottoman army at the battle of Kars in August 1745. The war disintegrated. Nader Shah grew insane and started to punish his own subjects, which led to a revolt from early 1745 to June 1746. In 1746 peace was made. The boundaries were unchanged and Baghdad remained in Ottoman hands. Nader Shah dropped his demand for Ja'fari recognition. The Porte was pleased and dispatched an ambassador but before he could arrive, Nader Shah was assassinated by his own officers.
