The reign of its most important ruler, Karim Khan, was marked by prosperity and peace. With its capital at Shiraz, arts and architecture flourished under Karim Khan's reign, with some themes in architecture being revived from the nearby sites of the Achaemenid (550–330 BC) and Sasanian (224–651 AD) era's of pre-Islamic Iran. The tombs of the medieval Persian poets Hafez and Saadi Shirazi were also renovated by Karim Khan. Distinctive Zand art which was produced at the behest of the Zand rulers became the foundation of later Qajar arts and crafts. Following the death of Karim Khan, Zand Iran went into decline due to internal disputes amongst members of the Zand dynasty. Its final ruler, Lotf Ali Khan Zand (1789–1794), was eventually executed by Agha Mohammad Khan Qajar (1789–1797) in 1794.
