After the Georgian republic fell to the Bolshevik invasion in 1921, Sologashvili became involved in underground political opposition to the new regime. She was member of the Women's Committee of the Social Democratic Party of Georgia, which provided aid to political prisoners and their families. In 1922, the Committee was transformed into a multi-party underground organization, the Georgian Political Red Cross. After the futile anti-Soviet revolt in 1924, she was no more politically active and worked as a teacher in the recently created South Ossetian Autonomous Oblast. At the height of Stalinist Great Purge in 1937, Sologashvili was arrested and hastily tried by the NKVD troika for "anti-Soviet propaganda", "chauvinism", and ties with the emigre politician Noe Ramishvili. She was executed by firing squad the same year.
