After the February Revolution in Russia, Avalishvili was named a Senator by the Provisional Government in May 1917.
He conducted important diplomatic work for the country as a member of the Georgian delegation to the 1919 Paris Peace Conference.
The Red Army invasion of Georgia forced Avalishvili into exile in March 1921.
He was one of the founding members of the Georgian Association in Germany and worked for the editorial boards of historical journals Georgica (London) and Byzantion (Brussels).
Much of the works is in diary form, the author being judiciously critical of ineptitude of the Caucasian governments.
