History lessons can be used as state-sponsored propaganda, distorting the events of the past  History taught in schools sometimes involves flagrant distortion of historical evidence either by the State or by individual teachers. Attempts may be made to avoid nasty aspects of a nation's past (e.g. the massacre of Chinese civilians by Japanese soldiers at Nanking in 1937) and/or to put down other peoples (e.g. the presentation of Australian Aboriginals as uncivilized until the 1960s). Japan's attempt to erase the memory of Nanking in its schoolchildren began in 1950s when it banned a third of all textbooks and 'Nanking Massacre simply disappeared' from their history1. As well as these extreme examples, low-level anti-Americanism is arguably pervasive in modern French school textbooks, reflecting tensions between France and the USA arising from the latter's Gaullist heritage and the recent "War on Terror". It is highly undesirable for school pupils to be exposed to misinformation peddled in History classes, which can lead to violence, hatred or discrimination. 1 Chapel, Joseph.
