While Karim was ruler, Persia recovered from the devastation of 40 years of war, providing the war ravaged country with a renewed sense of tranquility, security, peace, and prosperity. The years from 1765 to Karim Khan's death in 1779 marked the zenith of Zand rule. During his reign, relations with Britain were restored, and he allowed the East India Company to have a trading post in southern Iran. He made Shiraz his capital and ordered the construction of several architectural projects there. Karim Khan later died on 1 March 1779, having been ill for six months, most likely due to tuberculosis. He was buried three days later in the "Nazar Garden", now known as the Pars Museum.
