Beria At The NKVD
In August 1938, Stalin brought Beria to Moscow as deputy head of the People's Commissariat for Internal Affairs (NKVD), the ministry which oversaw the state security and police forces. Under Nikolai Yezhov, the NKVD carried out the Great Purge: the imprisonment or execution of millions of people throughout the Soviet Union as alleged "enemies of the people". By 1938, however, the oppression had become so extensive that it was damaging the infrastructure, economy and even the armed forces of the Soviet state, prompting Stalin to wind the purge down. Stalin had thoughts to appoint Lazar Kaganovich as head of the NKVD, but chose Beria probably because he was a professional secret policeman. In September, Beria was appointed head of the Main Administration of State Security (GUGB) of the NKVD, and in November he succeeded Yezhov as NKVD head (Yezhov was executed in 1940). The NKVD was purged next, with half its personnel replaced by Beria loyalists, many of them from the Caucasus.
Although Beria's name is closely identified with the Great Purge because of his activities while deputy head of the NKVD, his leadership of the organisation marked an easing of the repression begun under Yezhov. Over 100,000 people were released from the labour camps. The government officially admitted that there had been some injustice and "excesses" during the purges, which were blamed entirely on Yezhov. The liberalisation was only relative: arrests and executions continued, and in 1940, as war approached, the pace of the purges again accelerated. During this period, Beria supervised deportations of people identified as political enemies from Poland and the Baltic states after Soviet occupation of those regions.
In March 1939, Beria became a candidate member of the Communist Party's Politburo. Although he did not become a full member until 1946, he was already one of the senior leaders of the Soviet state. In 1941 Beria was made a Commissar General of State Security, the highest quasi-military rank within the Soviet police system of that time, effectively comparable to a Marshal of the Soviet Union.
On 5 March 1940, after the Gestapo–NKVD Third Conference was held in Zakopane, Beria sent a note (no. 794/B) to Stalin in which he stated that the Polish prisoners of war kept at camps and prisons in western Belarus and Ukraine were enemies of the Soviet Union, and recommended their execution. Most of them were military officers, but there were also intelligentsia, doctors, and priests for a total of over 22,000. With Stalin's approval, Beria's NKVD liquidated them in the Katyn massacre.
In October 1940 – February 1942, the NKVD under Beria carried out a new purge of the Red Army and related industries. In February 1941, Beria became Deputy Chairman of the Council of People's Commissars, and in June, following Nazi Germany's invasion of the Soviet Union, he became a member of the State Defense Committee (GKO). During World War II, he took on major domestic responsibilities and mobilized the millions of people imprisoned in NKVD Gulag camps into wartime production. He took control of the manufacture of armaments, and (with Georgy Malenkov) aircraft and aircraft engines. This was the beginning of Beria's alliance with Malenkov, which later became of central importance.
In 1944, as the Germans were driven from Soviet soil, Beria was in charge of dealing with the various ethnic minorities accused of collaboration with the invaders, including the Chechens, the Ingush, the Crimean Tatars and the Volga Germans. All these groups were deported to Soviet Central Asia. (See "Population transfer in the Soviet Union".)
In December 1944, Beria's NKVD was assigned to supervise the Soviet atomic bomb project ("Task No. 1"), which built and tested a bomb by 29 August 1949. In this capacity, he ran the successful Soviet espionage campaign against the atomic weapons program of the United States, which obtained much of the technology required. His most important contribution was to provide the necessary workforce for this project, which was extremely labour-intensive. At least 330,000 people, including 10,000 technicians, were involved. The Gulag system provided tens of thousands of people for work in uranium mines and for the construction and operation of uranium processing plants. They also constructed test facilities, such as those at Semipalatinsk and in the Novaya Zemlya archipelago. The NKVD also ensured the necessary security for the project. Amazingly, the physicist Pyotr Kapitsa refused to work with Beria even after he gave him a hunting rifle as a gift. It is notable that Stalin backed Kapitsa in this quarrel.
In July 1945, as Soviet police ranks were converted to a military uniform system, Beria's rank was officially converted to that of Marshal of the Soviet Union. Although he had never held a traditional military command, Beria made a significant contribution to the victory of the Soviet Union in World War II through his organization of wartime production and his use of partisans. Stalin personally never thought much of it, and neither commented publicly on his performance nor awarded him recognition (i.e. Order of Victory) as he did for most other Soviet Marshals.
