In 1919, he returned to his homeland. Here he was actively engaged in organizational activities. Grigoriev worked in a tense social, creative and organizational atmosphere, helping with advice, searching for material resources and organizing exhibitions. With his participation a decorative art workshop and art school appeared in Kozmodemyansk. It was at that time that the museum was established, which became the first museum to open in the Volga region in the difficult post-revolutionary years. 

In the 1920s, Grigoriev worked in Moscow and was one of the founders of the Association of the Artists of Revolutionary Russia. He was engaged in a lot of administrative work, took part in exhibitions. 

Reproduction of ‘Lilac. On the veranda’ was created in a difficult period of the artist’s life. It was written in Tarusa shortly before the arrest and subsequent exile to the camps for many years. In 1938, he was convicted of anti-Soviet activities and spent the following eight years in Kazakhstan. Grigoriev knew many statesmen of the Soviet Union, including Marshal of the Soviet Union Kliment Voroshilov. He wrote to him with a request to reconsider his case after being subjected to repression, but it did not bring any results. 

After liberation in 1946, the label “enemy of the people” was not removed. He couldn’t live in Moscow and he came back to Tarusa. For several years he lived there, in his house, half destroyed by the Germans, earning money by writing signs for diners and cafes. In 1954 he was rehabilitated. He was buried at Novodevichy Cemetery in Moscow.
