Question: The March 1956 demonstrations (also known as the 1956 Tbilisi riots or 9 March massacre) in the Georgian SSR were a series of protests against Nikita Khrushchev's de-Stalinization policy, Khrushchev was a Soviet politician who led the Soviet Union during part of the Cold War as the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964, and as Chairman of the Council of Ministers, or Premier, from which years time span?
Context: The First Secretary of the Adjar regional branch of the Communist Party of the Soviet Union was the position of highest authority in the Adjar ASSR in the Georgian SSR of the Soviet Union.  The position was created in 1921, and abolished in 1991.  The First Secretary was a de facto appointed position usually by the Politburo or the General Secretary himself. Nikita Sergeyevich Khrushchev (15 April [O.S. 3 April] 1894  – 11 September 1971) was a Soviet politician who led the Soviet Union during part of the Cold War as the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964, and as Chairman of the Council of Ministers, or Premier, from 1958 to 1964.  Khrushchev was responsible for the de-Stalinization of the Soviet Union, for backing the progress of the early Soviet space program, and for several relatively liberal reforms in areas of domestic policy.  Khrushchev's party colleagues removed him from power in 1964, replacing him with Leonid Brezhnev as First Secretary and Alexei Kosygin as Premier. The Anti-Party Group (Russian: Антипартийная группа , "Antipartiynaya gruppa" ) was a group within the leadership of the Communist Party of the Soviet Union that unsuccessfully attempted to depose Nikita Khrushchev as First Secretary of the Party in June 1957.  The group, given that epithet by Khrushchev, was led by former Premiers Georgy Malenkov and Vyacheslav Molotov.  The group rejected both Khrushchev's liberalisation of Soviet society and his denunciation of Joseph Stalin. The Council of Ministers of the Lithuanian SSR (Lithuanian: "Lietuvos TSR Ministrų Taryba" ) or Council of People's Commissars in 1940–46 (Lithuanian: "Lietuvos TSR Liaudies Komisarų Taryba" ) was the cabinet (executive branch) of the Lithuanian SSR, one of the republics of the Soviet Union.  Its structure and functions were modeled after the Council of People's Commissars and Council of Ministers of the Soviet Union.  The Council consisted of a chairman, first vice-chairman, vice-chairmen, ministers, and chairmen of state committees.  The council's chairman was equivalent to a prime minister and was second in rank after the First Secretary of the Communist Party of Lithuania. On 14 April 1978, demonstrations in Tbilisi, capital of the Georgian SSR, took place in response to an attempt by the Soviet government to change the constitutional status of languages in Georgia.  After a new Soviet Constitution was adopted in October 1977, the Supreme Soviet of the Georgian SSR considered a draft constitution in which, in contrast to the Constitution of 1936, Georgian was no longer declared to be the sole State language.  A series of indoor and outdoor actions of protest ensued and implied with near-certainty there would be a clash between several thousands of demonstrators and the Soviet government, but Georgian Communist Party chief Eduard Shevardnadze negotiated with the central authorities in Moscow and managed to obtain permission to retain the previous status of the Georgian language. The March 1956 demonstrations (also known as the 1956 Tbilisi riots or 9 March massacre) in the Georgian SSR were a series of protests against Nikita Khrushchev's de-Stalinization policy, which shocked Georgian supporters of Marxist–Leninist–Stalinist ideology.  The center of the protests was the republic's capital, Tbilisi, where spontaneous rallies to mark the third anniversary of Stalin's death and to protest Khrushchev's denunciation of Stalin quickly evolved into an uncontrollable mass demonstration and rioting which paralyzed the city.  Soon, political demands such as the change of the central government in Moscow and calls for the independence of Georgia from the Soviet Union appeared. Gaioz Devdariani (Georgian: გაიოზ დევდარიანი ) (February 2, 1901 – 1938) was a prominent Georgian revolutionary, Soviet politician, member of the Georgian National Academy of Sciences and a victim of the Great Purge of 1937.  Devdariani was born in the village of Kharagauli, Western Georgia into a large family.  In 1919, Devdariani was arrested by the Menshevik Government of Georgia for plotting and masterminding an insurrection against the democratically elected government.  He was imprisoned in Metekhi but managed to escape from the prison in 1920.  Between 1921 and 1923, Devdariani worked in various communist ministries of Georgian SSR.  From 1929 to 1931 Devdariani became the first Minister of Education of the Georgian SSR.  During the same year Devdariani became the honorable member of the Georgian National Academy of Sciences in the department of Economics.  After only a year as a Minister, he was promoted to the First Secretary of the Communist Party of the Georgian SSR.  However, soon after his appointment, Lavrentiy Beria (Communist Party Secretary of Transcaucasia) started agitations and provocations against Gaioz. "On the Cult of Personality and Its Consequences" (Russian: «О культе личности и его последствиях» , «"O kul'te lichnosti i ego posledstviyakh"») was a report by Soviet leader Nikita Khrushchev made to the 20th Congress of the Communist Party of the Soviet Union on 25 February 1956.  Khrushchev's speech was sharply critical of the reign of deceased General Secretary and Premier Joseph Stalin, particularly with respect to the purges which had especially marked the last years of the 1930s.  Khrushchev charged Stalin with having fostered a leadership personality cult despite ostensibly maintaining support for the ideals of communism. Khrushchev: The Man and His Era is a 2003 biography of Soviet leader Nikita Khrushchev.  Written by William Taubman, the book is the first in-depth and comprehensive American biography of Khrushchev.  Taubman was the recipient of the 2004 Pulitzer Prize for Biography or Autobiography, as well as the 2004 National Book Critics Circle Award.  The author spent almost 20 years researching the life of Khrushchev in preparation to write the book.  Extensive research was made possible through access to archives in Russia and the Ukraine, which were opened to the public following the collapse of the Soviet Union.  In addition to printed materials and documentation, he spent time engaging Khrushchev's children and extended relatives, resulting in over 70 personal interviews.  Taubman presents a historical narrative and study of the life of Nikita Khrushchev, the Soviet leader who succeeded Joseph Stalin.  The book concludes with Khrushchev's death on September 11, 1971. The First Secretary of the Abkhaz regional branch of the Communist Party of the Soviet Union was the position of highest authority in the SSR Abkhazia (1921–1931) and the Abkhaz ASSR (1931–1991) in the Georgian SSR of the Soviet Union.  The position was created on February 14, 1921, and abolished in 1991.  The First Secretary was a de facto appointed position usually by the Politburo or the General Secretary himself.
