The Doctors' plot (Russian: дело врачей, "doctors' case", врачи-вредители, "doctors-saboteurs" or врачи-убийцы, "doctors-killers") was an episode of antisemitism in the Soviet Union under Joseph Stalin's regime. In 1952–1953, a group of prominent Moscow doctors (predominantly Jews) were accused of conspiring to assassinate Soviet leaders. This was later accompanied by publications of anti-Semitic character in the media, which talked about the threats of Zionism and condemned people with Jewish names. Many doctors, officials and others, both Jews and non-Jews, were promptly dismissed from their jobs and arrested. A few weeks after the death of Stalin, the new Soviet leadership stated a lack of evidence and the case was dropped. Soon after, the case was declared to have been fabricated.
A number of theories attempt to explain the origins of the Doctors' plot case. Historians typically relate it to the earlier case of the Jewish Anti-Fascist Committee and to the campaign against the so-called rootless cosmopolitans in the second half of the 1940s, as well as to the power struggle within the Soviet leadership during that time.
In 1951, Ministry for State Security (MGB) investigator Mikhail Ryumin reported to his superior, Viktor Abakumov, minister of the MGB, that Professor Yakov Etinger, who was arrested as a "bourgeois nationalist" with connections to the Jewish Anti-Fascist Committee, had committed malpractice in treating Zhdanov (died 1948) and Shcherbakov (died 1945), allegedly with the intention of killing them. However, Abakumov refused to believe the story. Etinger died in prison (2 March 1951) due to interrogations and harsh conditions. Ryumin was then dismissed from his position in the MGB for misappropriating money and was held responsible for the death of Etinger. With the assistance of Malenkov, Ryumin wrote a letter to Stalin, accusing Abakumov of killing Etinger in order to hide a conspiracy to kill off the Soviet leadership. On 4 July 1951 the Politburo set up a commission (headed by Malenkov and including Beria) to investigate the issue. Based on the commission's report, the Politburo soon passed a resolution on the "bad situation in the MGB" and Abakumov was fired.
