There has never been a book about the ‘History of men in the Middle Ages’, nor is it likely that there ever will be one. But apart from the fact that far too many books about the Middle Ages make no mention of the part played by the women, leaving a lacuna in the description of medieval society, is there any justification for a special study to be made of the history of women in the High and Late Middle Ages? In the extremely hierarchical medieval society the social classes differed greatly from each other in their legal rights, economic circumstances and modes of living. Was there any condition that was shared by all women in medieval society? Nowadays, despite the remaining diversity in the status and way of life of women in the different social classes, some sociologists have defined them collectively as a ‘minority group’, although not necessarily a numerical one; others, rather more reasonably, use the term ‘marginal social group’.1 But let us discard the terminology of modern sociologists and examine the contemporary definitions that were applied in the Middle Ages.
