Lenin wanted the testament to be read out at the 12th Party Congress of the Communist Party of the Soviet Union, to be held in April 1923. However, after Lenin's third stroke in March 1923 that left him paralyzed and unable to speak, the testament was kept secret by his wife, Nadezhda Krupskaya, in the hope of Lenin's eventual recovery. She possessed four copies while Maria Ulyanova, Lenin's sister, had one. It was only after Lenin's death, on January 21, 1924, that she turned the document over to the Communist Party Central Committee Secretariat and asked for it to be made available to the delegates of the 13th Party Congress in May 1924. Krupskaya wanted the document circulated as widely as possible, in hopes of humiliating Stalin.
