In 1926-1932 Gvaladze was a member of the Board of the Defending Lawyers of Georgia, and lectured at the Pedagogical Institute in Gori from 1935 to 1937. His articles were systematically published in the Georgian press of 1916-1928. In 1921-1932 Gvaladzes journalistic papers were published in the Georgian emigrant press also ("Tavisupali Sakartvelo", "Tetri Giorgi", etc. Pseudonyms: "G.", "Geno", etc.). In spite of continuing social activity under the Soviet government, he never abandoned his political positions and led, from 1926, the underground conspirative group of the Georgian national political organization Tetri Giorgi. Earlier, on May 26, 1922, on the fourth anniversary of the independence of Georgia, he was one of the organizers of the first mass anti-Soviet demonstration in Tbilisi and was arrested by the GPU. In 1923, he joined an underground anti-Bolshevik bloc of the Georgian political opposition known as the Committee for Independence of Georgia and represented it in the Kakheti district where he was involved in preparation of an armed rebellion in August, 1924. He was arrested on September 5, 1924, but was released due to a declared amnesty in March, 1925. On August 10, 1937, during the Great Purge, he was rearrested along with his associates from the "Tetri Giorgi" conspirative group and shot in Tbilisi on October 15, 1937.
