1989: The recent past soon becomes history; a generation grows up that has no direct experience of the way things were. Almost half – 49 per cent – of young Romanians questioned by a survey in 2010 were uncertain whether political repression had existed in their country under communism. In neighbouring Bulgaria, a survey of 15- to 35-year-olds in 2013 found that the expression “Iron Curtain” had no specific meaning for 65.7 per cent of them, while “Gulag” meant nothing to 79.2 per cent (although 3.1 per cent thought it was an Internet search engine).
