 Stalin took charge of the funeral and was one of its pallbearers; against the wishes of Lenin's widow, the Politburo embalmed his corpse and placed it within a mausoleum in Moscow's Red Square.It was incorporated into a growing personality cult devoted to Lenin, with Petrograd being renamed "Leningrad" that year.To bolster his image as a devoted Leninist, Stalin gave nine lectures at Sverdlov University on the "Foundations of Leninism", later published in book form.
