25th July 1870 was the date the final reading was passed on the the Elementary Education Act 1870. The Acts aim was to provide a consistent level of education to children of all social classes throughout Wales, with attendance made compulsory to the age of ten. However it is seen by many to be one of the most damaging pieces of legislation in the social history of the Welsh language, as very often children spoke only Welsh and all teaching was done through the medium of English. To dissuade children from speaking Welsh, the Welsh Not was used a punishment in some schools. It was a piece of wood, inscribed with the letters 'WN' which was hung around the neck of children who were overheard to speak Welsh during the school day and passed on from child to child until at the end of the day, the wearer of the 'not' would be given a lashing.
