Editing Kim Il-sung (section)

=== Controversy about origins ===
Controversy surrounds Kim's life before the founding of North Korea, with some labeling him an impostor. Several sources indicate that the name "Kim Il-sung" had previously been used by a prominent early leader of the Korean resistance, Kim Kyung-cheon. The Soviet officer Grigory Mekler, who worked with Kim during the Soviet occupation, said that Kim assumed this name from a former commander who had died. However, historian Andrei Lankov has argued that this is unlikely to be true.

Several witnesses knew Kim before and after his time in the Soviet Union, including his superior, Zhou Baozhong, who dismissed the claim of a "second" Kim in his diaries. Historian Bruce Cumings pointed out that Japanese officers from the Kwantung Army have attested to his fame as a resistance figure. Historians generally accept the view that, while Kim's exploits were exaggerated by the personality cult which was built around him, he was a significant guerrilla leader.
