The universities of Oxford and Cambridge were founded in 1167 and 1209 respectively, and general literacy continued to increase over the succeeding centuries, although books were still copied by hand and therefore very expensive. Over time, the commercial and political influence of the East Midlands and London ensured that these dialects prevailed (London had been the largest city for some time, and became the Norman capital at the beginning of the 12th Century), and the other regional varieties came to be stigmatized as lacking social prestige and indicating a lack of education. The 14th Century London dialect of Chaucer, although admittedly difficult, is at least recognizable to us moderns as a form of English, whereas text in the Kentish dialect from the same period looks like a completely foreign language.
