Boris Pasternak's 1956 novel Doctor Zhivago tells the story of a Russian doctor living at the time of the 1917 Russian Revolution, which led to the establishment of the Soviet Union. Because the book dealt with hardships people faced after the revolution, publishers in the Soviet Union refused to release it, calling it anti-Soviet. Pasternak's solution was to have the book smuggled out of the Soviet Union and published in Europe. Though Soviet authorities tried to prevent it, the book was published in Italy in 1957 and was immediately well-received. In 1958, it was translated into English and went on to become one of the most popular novels of the 1950s.
