On August 12, ,1336 English King Edward III ended wool export to Flanders. An excerpt from the article:
"In time the larger landowners developed direct trading links with cloth manufacturers abroad, whereas by necessity the peasants continued to deal with the travelling wool merchants. Obviously, by cutting out the middle man and dealing in larger quantities, the landowners got a much better deal! Perhaps this is why it is said that the wool trade started the middle-class / working-class divide in England.
Successive monarchs taxed the wool trade heavily. King Edward I was the first. As the wool trade was so successful, he felt he could make some royal revenue to fund his military endeavours by slapping heavy taxes on the export of wool.
Realising the importance of these taxes to his royal coffers Edward III actually went to war with France, partly to help protect the wool trade with Flanders. The burghers from the rich Flemish cloth-towns had appealed to him for help against their French overlord. Although called the Hundred Year War, the conflict would actually last 116 years, from 1337 to 1453.
During this period the taxes that had been levied began to damage the wool trade, which ultimately resulted in more cloth being produced in England. Flemish weavers fleeing the horrors of war and French rule were encouraged to set up home in England, with many settling in Norfolk and Suffolk. Others moved to the West Country, the Cotswolds, the Yorkshire Dales and Cumberland where weaving began to flourish in the villages and towns."
