(1460-1485) A series of wars England and France fought after peace was made between them. Two families began to fight for the English throne: the Lancasters, using a red rose for their emblem, and the Yorks, who used a white rose. The conflict became known as this war because both sides used a rose as their symbol. At first the stockists were successful. However, Edward IV (Yorkist) took the throne and won victories over the Lancastrians. But when Edward died, his son disappeared and Edward's brother, Richard III, became king. Almost as soon as he was crowned the new king, Richard III faced uprisings such as the one led by Duke of Buckingham, who had originally helped Richard III gain the throne. After Richard III's death, a member of the Tudors (family) claimed the throne. Henry Tudor, becoming Henry VII, was related to both sides of the war. As a result of this war, England's economy, particularly the cloth economy, continued to flourish, London merchants assumed greater political prominence in governing and in banking, and England's population increased slowly but steadily.
