In March 1923, Lenin had a third stroke and lost his ability to speak; that month, he experienced partial paralysis on his right side and began exhibiting sensory aphasia. By May, he appeared to be making a slow recovery, regaining some of his mobility, speech, and writing skills. In October, he made a final visit to the Kremlin. In his final weeks, Lenin was visited by Zinoviev, Kamenev, and Bukharin; the latter visited him at his Gorki mansion on the day of his death. On 21 January 1924, Lenin fell into a coma and died later that day at age 53.His official cause of death was recorded as an incurable disease of the blood vessels.
The Soviet government publicly announced Lenin’s death the following day. On 23 January, mourners from the Communist Party, trade unions, and Soviets visited his Gorki home to inspect the body, which was carried aloft in a red coffin by leading Bolsheviks. Transported by train to Moscow, the coffin was taken to the House of Trade Unions, where the body lay in state. Over the next three days, around a million mourners came to see the body, many queuing for hours in the freezing conditions. On 26 January, the eleventh All-Union Congress of Soviets met to pay respects, with speeches by Kalinin, Zinoviev, and Stalin. Notably, Trotsky was absent; he had been convalescing in the Caucasus, and he later claimed that Stalin sent him a telegram with the incorrect date of the planned funeral, making it impossible for him to arrive in time. Lenin’s funeral took place the following day, when his body was carried to Red Square, accompanied by martial music, where assembled crowds listened to a series of speeches before the corpse was placed into the vault of a specially erected mausoleum. Despite the freezing temperatures, tens of thousands attended.
Against Krupskaya’s protestations, Lenin’s body was embalmed to preserve it for long-term public display in the Red Square mausoleum.During this process, Lenin’s brain was removed; in 1925 an institute was established to dissect it, revealing that Lenin had had severe sclerosis. In July 1929, the Politburo agreed to replace the temporary mausoleum with a permanent one in granite, which was finished in 1933.His sarcophagus was replaced in 1940 and again in 1970.For safety amid the Second World War, from 1941 to 1945 the body was temporarily moved to Tyumen. As of 2023, his body remains on public display in Lenin’s Mausoleum on Red Square.
