The economy of England in the Middle Ages, from the Norman invasion in 1066, to the death of Henry VII in 1509, was fundamentally agricultural, though even before the invasion the local market economy was important to producers. Norman institutions, including serfdom, were superimposed on an existing system of open fields and mature, well-established towns involved in international trade. Over the five centuries of the Middle Ages, the English economy at first grew and then suffered an acute crisis, resulting in significant political and economic change. Despite economic dislocation in urban and extraction economies, including shifts in the holders of wealth and the location of these economies, the economic output of towns and mines developed and intensified over the period. By the end of the period, England had an economy dominated by rented farms controlled by gentry, and a thriving community of merchants and corporations.
The 12th and 13th centuries saw a small development of the English economy. This was partially driven by the growth in the population from around 1.5 million at the time of the creation of the Domesday Book in 1086 to between 4 and 5 million in 1300. England remained a primarily agricultural economy, with the rights of major landowners and the duties of serfs increasingly enshrined in English law. More land, much of it at the expense of the royal forests, was brought into production to feed the growing population or to produce wool for export to Europe. Many hundreds of new towns, some of them planned, sprung up across England, supporting the creation of guilds, charter fairs and other important medieval institutions. The descendants of the Jewish financiers who had first come to England with William the Conqueror played a significant role in the growing economy, along with the new Cistercian and Augustinian religious orders that came to become major players in the wool trade of the north. Mining increased in England, with the silver boom of the 12th century helping to fuel a fast-expanding currency.
