Even I, who was born in the USSR with difficulty and normally refers to that period of my life, remembered who he was and why they once put up a monument to him. Synonyms for him are "the third from the end", "the old man in the position of headman", "the main one in the general choir"... It would be better if instead of it, the monument of a country gone forever, the legacy of a bygone era, they would replace it, make a memorial monument to the victims and liberators of Minsk from the Nazi aggressors, it would be at least for our memory...
I understand if this monument had been erected before 1953 or at least immediately after Kalinin's death in 1946, but it was already 1978, that is, the heyday of stagnation. Probably, the sculptor could only perpetuate his name by creating such a masterpiece. And as for this monument, nothing was found even on Wikipedia, except that Kalinin "on June 20, 1919, arriving in Minsk on a propaganda train, he made speeches on Troitskaya Gora and in the walls of the Opera and Ballet Theater."
