the other hand, small, dedicated militant parties and Marxist sects in the West took pride in knowing the theory; Hobsbawm says: "This was the milieu in which 'the clearness of a comrade could be gauged invariably from the number of earmarks on his Manifesto. Ubiquity, 1917–present Following the October Revolution of 1917 that swept the Vladimir Lenin-led Bolsheviks to power in Russia, the world's first socialist state was founded explicitly along Marxist lines. The Soviet Union, which Bolshevik Russia would become a part of, was a one-party state under the rule of the Communist Party of the Soviet Union (CPSU). Unlike their mass-based counterparts of the Second International, the CPSU and other Leninist parties like it in the Third International expected their members to know the classic works of Marx, Engels and Lenin. Further, party leaders were expected to base their policy decisions on Marxist-Leninist ideology. Therefore works such as the Manifesto were required reading for the party rank-and-file. Therefore the widespread dissemination of Marx and Engels' works became an important policy objective; backed by a sovereign state, the CPSU had relatively inexhaustible resources for this purpose. Works by Marx, Engels, and Lenin were published on a very large scale, and cheap editions of their works were available in several languages across the world. These publications were either shorter writings or they were compendia such as the various editions of Marx and Engels' Selected Works, or their Collected Works. This affected the destiny of the Manifesto in several ways. Firstly, in terms of circulation; in 1932 the American and British Communist Parties printed several hundred thousand copies of a cheap edition for "probably the largest mass edition ever issued in English". Secondly the work entered political-science syllabuses in universities, which would only expand after the Second World War. For its centenary in 1948, its publication was no longer the exclusive domain of Marxists and academicians; general publishers too printed the Manifesto in large numbers. "In short, it was no longer only a classic Marxist document", Hobsbawm noted, "it had become a political classic tout court". Total sales have been estimated at 500 million, and one of the four best-selling books of all time. Even after the collapse of the Soviet Bloc in the 1990s, the Communist Manifesto remains ubiquitous; Hobsbawm says that "In states without censorship, almost certainly anyone within reach of a good bookshop, and certainly anyone within reach
