In lieu of Russia's failure to honour the terms of the Treaty of Georgievsk, Qajar Iran reinvaded Georgia and captured and sacked Tbilisi. Georgian rulers felt they had nowhere else to turn now as Georgia was again re-subjugated by Iran. Tbilisi was captured and burnt to the ground, and eastern Georgia reconquered. However, Agha Mohammad Khan, Persia's ruler, was assassinated in 1797 in Shusha, after which the Persian grip on Georgia softened again. Erekle, King of Kartli-Kakheti, still dreaming of a united Georgia, died a year later. After his death, a civil war broke out over the succession to the throne of Kartli-Kakheti, and one of the rival candidates called on Russia to intervene and decide matters. On 8 January 1801, Tsar Paul I signed a decree on the incorporation of Georgia (Kartli-Kakheti) within the Russian Empire, which was confirmed by Tsar Alexander I on 12 September 1801. The Georgian envoy in Saint Petersburg, Garsevan Chavchavadze, reacted with a note of protest that was presented to the Russian vice-chancellor Alexander Kurakin. In May 1801, Russian General Carl Heinrich von Knorring removed the Georgian heir to the throne, David Batonishvili, from power and deployed a provisional government headed by General Ivan Petrovich Lazarev.
