The rebellion of Wat Tyler was encouraged by the people of London, according to Froissart, who repeats what he heard and clearly echoes the rumours prevalent at the Court. The Londoners, he says, invited the country people to assemble and to march upon London, where they promised them a good reception and such a welcome that there should soon be not a slave left in all England—but there were none in London. The people came up from all parts of the Kingdom; they came in companies of a dozen or a hundred. Froissart says they knew not what they wanted; it is, however, quite certain that they wanted to realise the dream of their preachers; they wanted, what people always want, justice; they wanted to see the life of religion instead of the profession of religion, and they knew very well what the life of religion meant; they wanted a more equitable division of the world’s goods. The great rebellion of Wat Tyler, if it was really encouraged, welcomed, or invited by the common people of London, which I doubt, further than that there were certainly some who had imbibed the ideas of John Ball, shows us what the common people thought. As for the extent of their knowledge and its limitations, London was a place of foreign trade, and the centre of internal trade. It was therefore filled with people carrying on the trade of distribution, collection, import, and export. In other words, it was constantly receiving and sending forth men to foreign countries across the sea and to all parts of the realm of England to carry on their trade. The boys went down to the quays to talk with the sailors and the stevedores: they learned to distinguish the Genoese and the Venetian galleys, the ships of the Hanseatic League, the ships from Lisbon and the ships from Bordeaux, they heard where these places were, and what they sent to London. The voyagers themselves in the taverns told their travellers’ tales. All that trade could teach the people was learned by them in the fourteenth century as well as in the nineteenth. I suppose that they would not be able to draw a _mappa mundi_ with much approach to accuracy, but they knew where places were. Their knowledge of geography and of peoples was widened also by their pilgrimages and by the stories told by pilgrims on their return. As to science, each man had the mastery of his craft: that was enough for him. As to history, the people of London remembered; no doubt they mixed up a good many events, but they remembered at least their own liberties. Of books they had none and could not read; of songs satirical, historical, commemorative, they had, of their own, a good many which are still surviving. It will be understood from the foregoing what were the rough ideas of the people as to religion and social economy; how their knowledge of the world was considerable; how their trades taught them a certain amount of science; and how their popular songs extended and deepened and strengthened the popular ideas.
