After several change of powers and withdrawal of the Denikin's forces in December 1919 the Bolsheviks permanently established themselves in Kyiv. With the second arrival of Bolsheviks Vernadsky resigned. Orest Levytskyor was elected President of the Academy for the next couple of years. In 1921 Levytsky was replaced by a newly elected Mykola Vasylenko, however he was not approved by the authorities and soon was replaced with Levytsky. Vasylenko after that was arrested in 1923 and convicted (later released on amnesty).
