Looking at Tertitsky's article, what sources does he use to discuss the early history of Kim Ilsung? What are the strengths and weaknesses of these sources? Historical literature may vary it’s characteristics by which perspective the recorder had viewed the current state. For example, during the communist regime of Soviet Russia, it was forbidden to write, record anything against their ideology, so, we rarely find Russian(Soviet) articles criticizing their government. For the other example, one of the versions of ‘Three Kingdom’ the author originated from Shu Han would represent their leaders as heroes who saved citizens and other dynasties as an evil nation. The main point here is, the In the research of Kim Ilsung’s early history, Tertitsky had used Bol’shaya sovetskaya entsiklopediya [The Great Soviet encyclopedia-1953], and second volume of the Entsiklopedicheskiy slovar’ [Encyclopaedic dictionary-1954] of as a source. His early years had also been recorded in Malaya sovetskaya entsiklopediya [Concise Soviet encyclopedia]. Here, however, all the sources are from communist official documents(or equivalent), this may distort the main objective of the research. Before listing which source he used, he had firmly stated that very minimal sources were used for the research since most aren't available in present day. “Kim’s pre-1945 activities have not been well researched…the surviving documents about the early period of Kim’s life remained in Soviet or Chinese archives which for decades were closed to researchers.“(Tertitsky, 2019, pg.112) Therefore, in the case of his research, mostly the documents that could be used for apotheosizing Ilsung would survive. Additionally, under communist’s strict censoring of literature, anything criticizing his traits must have been destroyed or distorted in a way (we’ll never know). “An additional problem was that after Kim Il-sung came to power, his biography was heavily distorted by North Korean authorities for the purpose of aggrandizing his personage. (Tertitsky, 2019, pg.113)So with limited resources, the Kim Ilsung studied by Tertitsky could only be the tip of the iceberg. The history is so called the story of victor’s. I think this really well represents the situation here.
