The "Treachery of the Blue Books" was a report made by a commission of young English jurists who visited Wales in the late 1840s. Its full name is "Reports of the Commission of Inquiry into the State of Education in Wales". It was made in response to rising political violence as a result of land enclosures and the efforts of the Anglican church to proliferate and control schools for the poor.
It lambasted the Welsh language, saying that no Welsh literary tradition existed worthy of the name. It reported that the Welsh people had potential for "progress" and a strong perceptive ability, but were held back by their "backwards" language, called a source of moral decline. It criticized the nonconformity of the Welsh church.
It recommended banning publications in the Welsh language and establishing state schools that would teach only in English, to rid the region of cultural distinctiveness and forcibly assimilate the Welsh people into English culture to prevent labor uprisings in a valuable coal and steel producing region.
It served as a blueprint for cultural genocide elsewhere in the British Empire. The report should be read to get a glimpse into the nature of the methods employed by colonialists and the thinking that underlies it.
