Mythical Soviet boy whistleblower.

(Russian: Па́вел Трофи́мович Моро́зов; November 14, 1918 – September 3, 1932; better known by diminutive Pavlik) Soviet youth glorified by the Soviet Union propaganda as a martyr. His story, dated to 1932, is that of a 13-year old boy who denounced his father to the authorities and was in turn killed by his family. It was a Soviet morality tale: opposing the state was selfish and reactionary, and state was more important than family. His story was a subject of compulsory children readings, songs, plays, a symphonic poem, a full-length opera and six biographies. There is very little original evidence related to the story, much of it a hearsay provided by second-hand witnesses. According to modern research, the story (denunciation, trial) is most likely a fictional tale, although there is little doubt that Pavlik was a real child who was murdered in some domestic quarrel.

Comment: An offbeat and fictional example, in the end more about doctrinal conformity than whistleblowing. Perhaps interesting nonetheless to have a Soviet example.
