Consanguinity, or blood-relatedness, was one of the most important criteria which determined the formation of marriage in the medieval era. Unfortunately, there is no comprehensive study in English which describes the development of consanguinity prohibitions and which explains fully the types of kinship calculation used as a part of the restrictions which developed. In order to fill this void, my goal in this thesis has been to offer a well-researched, comprehensive study of this topic.

I have examined the studies completed by other researchers and combined any pertinent information from those sources with my own research on medieval attitudes and policies regarding marriage. I have also attempted to provide kinship calculation charts which are easily understood and which can serve as an aid to the understanding of actual medieval consanguinity charts from manuscripts.
