Treaty of Georgievsk
Following the Treaty of Georgievsk (1783) and Agha Mohammad Khan Qajar's brief re-occupation of eastern Georgia, the Kingdom of Kartli-Kakheti was annexed by the Russian Empire in 1800. The former warring royal houses of the various Georgian kingdom were mostly incorporated into the Russian nobility, thereby losing their quasi-royal status, and becoming subsumed into the Russian empire's service nobility.
