In July 1846, three commissioners, R.R.W. Lingen, Jellynger C. Symons and H.R. Vaughan Johnson, were appointed to inquire into the state of education in Wales; the Commissioners were all Anglicans and thus presumed unsympathetic to the nonconformist majority in Wales. The Commissioners presented their report to the Government on 1 July 1847 in three large blue-bound volumes. This report quickly became known as the Treachery of the Blue Books () since, apart from documenting the state of education in Wales, the Commissioners were also free with their comments disparaging the language, nonconformity, and the morals of the Welsh people in general. An immediate effect of the report was that ordinary Welsh people began to believe that the only way to get on in the world was through the medium of English, and an inferiority complex developed about the Welsh language whose effects have not yet been completely eradicated. The historian Professor Kenneth O. Morgan referred to the significance of the report and its consequences as "the Glencoe and the Amritsar of Welsh history".
