With the Dissolution of the Monasteries, between 1536 and 1541, Furness and Fountains Abbeys were supplanted by new secular landlords for the farmers of Keswick and its neighbourhood. The buying and selling of sheep and wool were no longer centred on the great Abbeys, being handled locally by the new landowners and tenants. This enhanced Keswick's importance as a market centre, though at first the town remained only modestly prosperous: in the 1530s John Leland wrote of it as "a lytle poore market town". By the second half of the century, copper mining had made Keswick richer: in 1586 William Camden wrote of "these copper works not only being sufficient for all England, but great quantities of the copper exported every year" with, at the centre, "Keswicke, a small market town, many years famous for the copper works as appears from a charter of king Edward IV, and at present inhabited by miners".
