My understanding is that Ghengis Khan is still seen as a national hero and even worshipped as part of Mognolian shamanism up to this day (there are regular pilgrimages to his maosoleum in Inner Mongolia, China). While Mongolia was a socialist republic modelled on the USSR, how did the state deal with the popularity of Ghengis Khan? Was it wholly repressed as reactionary/chauvinist religion or was it similar to how the Ceaușescu government in Romania tried to rehabilitate Vlad the Impaler as a national figure and anti-imperialist for fighting the Ottomans?
