Margaret of Anjou was a heroine; not a heroine of romance and fiction, but of stern and terrible reality. Her life was a series of military exploits, attended with dangers, privations, sufferings, and wonderful vicissitudes of fortune, scarcely to be paralleled in the whole history of mankind.She was born and lived in a period during which there prevailed in the western part of Europe two great and dreadful quarrels, which lasted for more than a hundred years, and which kept France and England, and all the countries contiguous to them, in a state of continual commotion during all that time.The first of these quarrels grew out of a dispute which arose among the various branches of the royal family of England in respect to the succession to the crown. The two principal branches of the family were the descendants respectively of the Dukes of York and Lancaster, and the wars which they waged against each other are called in history the wars of the houses of York and Lancaster. These wars continued for several successive generations, and Margaret of Anjou was the queen of one of the most prominent representatives of the Lancaster line. Thus she became most intimately involved in the quarrel.
