The range and variety of Chaucer's English did much to establish English as a national language. Chaucer also contributed much to the formation of a standard English based on the dialect of the East Midlands region which was basically the dialect of London which Chaucer himself spoke. Indeed, by the end of the fourteenth century the educated language of London, bolstered by the economic power of London itself, was beginning to become the standard form of written language throughout the country, although the process was not to be completed for several centuries. The cultural, commercial, administrative and intellectual importance of the East Midlands (one of the two main universities, Cambridge, was also in this region), the agricultural richness of the region and the presence of major cities, Norwich and London, contributed much to the increasing standardisation of the dialect.
