Under Communism, the government cared a great deal about what you wrote. If you were part of the system, the government promoted your work. If you were against the system, the government censored you or possibly jailed you. In either case, though, the Communist governments took your words seriously -- as useful propaganda or potential threat.
In Hungary, in the 1970s and 1980s, the system was not quite that harsh. A second public sphere gradually opened up for those writers who did not toe the government line.
