The purpose of this study is to investigate women`s political activities and participation in the Middle Ages, which has been a scholarly lacuna. Medieval politics has been recognized as a male-dominated area from which women were totally excluded. Beatrice`s revolt against her husband provides a clue that women were actively involved in politics, and therefore the medieval female should not be evaluated as politically incompetent. Similar cases have also been observed in the lives of women in many great and small noble families. In these households, noblewomen assumed the roles and responsibilities of wives and mothers, but at the same time represented and protected the interests of their families of origin. These ambiguous attitudes are due to the fact that medieval marriage was more of a family union than one of personal affection, and many women attained political standing due to their kinship ties. In conclusion, the medieval relationships between wives and husbands can be understood within their family constellations. The revolt of Beatrice alludes to this interesting political and social structure in the twelfth century.
