The well-known national-political and party statesman Hovhannes Kajaz­nuni was one of the few Armenian politicians living in exile who could not with­stand homesickness, and, ignoring all sorts of dangers, nevertheless re­turned to Soviet Armenia. In the historiography of Kajaznuni there is a lot of ambiguous information about the years in Soviet Armenia: few people know about the fate of the great Armenian after returning to the homeland. In Soviet Armenia, he worked as a highly qualified architect, received the title of profes­sor, read lectures at the Technical Faculty of Yerevan University, and then at the Engineering Construction Institute. At the same time, he experienced deep dis­ap­pointment in his life, in the face of the negative phenomena of the "perso­nality cult" period. At the end of July of 1937, O. Kajaznuni was arrested, and on December 5 the k (USSR) ICRC Troika sentenced O. Kajaznuni as an active par­ti­cipant in the Dashnaktsutyun to death with the confiscation of his personal property. However, his execution was postponed on the basis of a diagnosis of tu­berculosis, delivered by the prison doctor. Shortly thereafter, on January 15, 1938, at the age of 70, the first Prime Minister of the Republic of Armenia, Hov­hannes Kajaznuni, died in the prison hospital.
