The War of the Roses
Following the Hundred Years War, England found itself in turmoil. The war had seriously weakened the monarchy, and drained much of the nation’s treasury. The nation was ruled by the house of Lancaster, which bore the emblem of a red rose. The Duke of York, whose family bore the emblem of a white rose, saw the king’s weakened state as an opportunity to seize power and establish himself as king.
For the next 30 years the house of Lancaster and the house of York would fight one another for control over England. In the end, the Duke of York was successful.
