The population was scanty, and increased little. When Henry VIII. came to the throne in 1509, London may have had forty or fifty thousand inhabitants, York eleven thousand, Bristol nine or ten thousand, and Norwich six thousand.[203] Paris at that time probably contained between three and four hundred thousand, and Milan and Ghent two hundred and fifty thousand each. But although England was not a monied centre during the Middle Ages, and perhaps for that very reason, she felt with acuteness the financial pressure of the fourteenth and fifteenth centuries. She had little gold and silver, and gold and silver rose in relative value; she had few manufactures, and manufactures were comparatively prosperous; her wealth lay in her agricultural interests, and farm products were, for the most part, severely pinched. Commenting on the prices between the end of the thirteenth century and the middle of the sixteenth, Mr. Rogers has observed:-- “Again, upon several articles of the first importance, there is a marked decline in the price from the average of 1261–1400 to that of 1401–1540. This would have been more conspicuous, if I had in my earlier volumes compared all prices from 1261 to 1350 with those of 1351–1400. But even over the whole range, every kind of grain, except wheat and peas, is dearer in the thirteenth and fourteenth centuries than it is in the first hundred and forty years of the present period [1401–1582]; and had I taken the average price of wheat during the last fifty years of the fourteenth century, it would have been (6s. 1 1⁄2d.) dearer than the average of 1401–1540 (5s. 11 3⁄4d.), heightened as this is by the dearness of the last thirteen years.”[204] The tables published by Mr. Rogers make it possible to form some idea of the strain to which the population of Great Britain was exposed, during the two hundred and fifty years which intervened between the crisis at the close of the thirteenth century, and the discovery of the mines of Potosi in 1545, which flooded the world with silver. Throughout this long interval an expanding commerce unceasingly enlarged the demand for currency, while no adequate additions were made to the stock of the precious metals; the consequence was that their relative value rose, while the value of commodities declined, and this process had a tendency to debase the coinage. The latter part of the Middle Ages was a time of rapid centralization, when the cost of administration grew from year to year but in proportion as the necessities of the government increased, the power of the people to pay taxes diminished, because the products which they sold brought less of the standard coin. To meet the deficit the same weight of metal had to be cut into more pieces, and thus by a continued inflation of the currency, general bankruptcy was averted. The various stages of pressure are pretty clearly marked by the records of the Mint.
