“According to Parallel Histories, a charity that aims to find new ways of teaching about recent conflicts, children studying the earlier period of 20th century history never learn that institutionalised discrimination against Catholics was written into the fabric of Northern Ireland’s laws since its creation in 1921. For those studying the later period, however, this is spelled out on the first page of the coursebook. Michael Davies, the charity’s founder, has been working with schools in Stoke-on-Trent and in Lancaster to help them find out which of the units Northern Irish schools teach. They found a definite bias along denominational lines: four out of 10 Protestant schools for which data was available taught the earlier unit, compared with just one in 10 Catholic schools.”
