Kingdom of Kartli-Kakheti
After 1801, when the Kingdom of Kartli-Kakheti (eastern Georgia) became part of the Russian Empire the region ended up in the Imperial Russian conquest in 1803, Saingilo was initially incorporated into Zakatal Okrug of Tiflis Governorate. From 1918 to 1920 both Democratic Republic of Georgia (DRG) and Azerbaijan Democratic Republic (ADR) claimed its territory as theirs, but the dispute never led to an armed confrontation. After the fall of the ADR in 1920, Soviet Russia and Azerbaijan SSR recognized it as part of Georgia, whose government granted these lands a degree of internal autonomy. Following the Red army invasion of Georgia in 1921, the area was officially transferred to the jurisdiction and control of the Azerbaijan SSR by the central communist government in Moscow in 1922.
