From Wikipedia about one more political Nobel award:
Aleksandr Solzhenitsyn was awarded the Nobel Prize in Literature in 1970.
He made the world aware of the Gulag, the Soviet Union's forced labor camp system, and for these efforts Solzhenitsyn was exiled from the Soviet Union in 1974.
After the KGB had confiscated Solzhenitsyn's materials in Moscow, during 1965-1967 the preparatory drafts of The Gulag Archipelago were turned into finished typescript in hiding at his friends homes in Estonia.
In 1969 Solzhenitsyn was expelled from the Union of Writers. In 1970, Solzhenitsyn was awarded the Nobel Prize in Literature. He could not receive the prize personally in Stockholm at that time, since he was afraid he would not be let back into the Soviet Union. Instead, it was suggested he should receive the prize in a special ceremony at the Swedish embassy in Moscow. The Swedish government refused to accept this solution, since such a ceremony and the ensuing media coverage might upset the Soviet Union and damage Sweden's relations with the superpower. Instead, Solzhenitsyn received his prize at the 1974 ceremony after he had been deported from the Soviet Union.
The Gulag Archipelago was a three-volume work on the Soviet prison camp system. It was based upon Solzhenitsyn's own experience as well as the testimony of 227 former prisoners and Solzhenitsyn's own research into the history of the penal system. It discussed the system's origins from the founding of the Communist regime, with Lenin himself having responsibility, detailing interrogation procedures, prisoner transports, prison camp culture, prisoner uprisings and revolts, and the practice of internal exile. The appearance of the book in the West put the word gulag into the Western political vocabulary and guaranteed swift retribution from the Soviet authorities.
