Assassination
Agha Muhammad was assassinated in 1797 in the city of Shusha, the capital of Karabakh khanate, after about 16 years in power. According to Hasan-e Fasa'i's' Farsnama-ye Naseri, during Agha Muhammad's stay in Shusha, one night "a quarrel arose between a Georgian servant named Sadeq and the valet Khodadad-e Esfahani. They raised their voices to such a pitch that the shah became angry and ordered both to be executed. Sadeq Khan-e Shaghaghi, a prominent emir, interceded on their behalf, but was not listened to. The shah, however, ordered their execution to be postponed until Saturday, as this happened to be the evening of Friday (the Islamic Sabbath), and ordered them back to their duties in the royal pavilion, unfettered and unchained, awaiting their execution the next day. From experience, however, they knew that the King would keep to what he had ordered, and, having no hope, they turned to boldness. When the shah was sleeping, they were joined by the valet Abbas-e Mazandarani, who was in the plot with them, and the three invaded the royal pavilion and with dagger and knife murdered the shah."
His nephew, crowned as Fath Ali Shah, succeeded him.
