Lenin
Vladimir Lenin was the founder and first leader of the Soviet Union (link to his Wikipedia page below). His body is displayed in a mausoleum in Red Square, directly next to the Kremlin. Russian state propaganda has espoused the debunked talking point that Lenin is responsible for the creation of modern-day Ukraine. Memes about Lenin will sometimes highlight this rhetoric, but most memes will refer to his burial place in connection with Ukrainian attacks, both past and predicted, on Moscow.
