measures carried out by Stalin that were actually a continuation of anti-democratic trends and measures implemented under Lenin…in so many ways, Stalin acted, not in line with Lenin's clear instructions, but in defiance of them." In doing so, some historians have tried to distance Stalinism from Leninism to undermine the totalitarian view that the negative facets of Stalin were inherent in communism from the start. Critics include anti-Stalinist communists such as Leon Trotsky, who pointed out that Lenin attempted to persuade the Communist Party to remove Stalin from his post as its General Secretary. Lenin's Testament, the document which contained this order, was suppressed after Lenin's death. In his biography of Trotsky, British historian Isaac Deutscher says that, on being faced with the evidence, "only the blind and the deaf could be unaware of the contrast between Stalinism and Leninism." A similar analysis is present in more recent works such as those of Graeme Gill, who argues that "[Stalinism was] not a natural flow-on of earlier developments; [it formed a] sharp break resulting from conscious decisions by leading political actors." However, Gill notes that "difficulties with the use of the term reflect problems with the concept of Stalinism itself. The major difficulty is a lack of agreement about what should constitute Stalinism." Revisionist historians such as Sheila Fitzpatrick have criticized the focus on the upper levels of society and the use of Cold War concepts such as totalitarianism which have obscured the reality of the system. Legacy Pierre du Bois argues that the cult was elaborately constructed to legitimize his rule. Many deliberate distortions and falsehoods were used. The Kremlin refused access to archival records that might reveal the truth, and critical documents were destroyed. Photographs were altered, and documents were invented. People who knew Stalin were forced to provide "official" accounts to meet the ideological demands of the cult, especially as Stalin presented it in 1938 in Short Course on the History of the All-Union Communist Party (Bolsheviks), which became the official history. Historian David L. Hoffmann sums up the consensus of scholars: "The Stalin cult was a central element of Stalinism, and as such, it was one of the most salient features of Soviet rule. [...] Many scholars of Stalinism cite the cult as integral to Stalin's power or as evidence of Stalin's megalomania." However, after Stalin died in 1953, his successor Nikita Khrushchev repudiated his policies and
