Abstract
Marriages have always been a kind of promise of a common future, not only in a romantic sense but also in a purely practical sense. It was not just a union between a man and a woman, as it often perceived contemporarily.
It was a union of entire families. While marriages may have been contracted for objective reasons it must always be assumed that they were not just an immediate solution.
In order to understand medieval society and the political situation, it is therefore imperative to pay attention to the consequences of marriage when conducting research on it. This study will attempt to summarise the lives of the last princesses of the House of Luxembourg, their significance in this process and how essential women's contacts with relatives were and that the family's matrimonial politics did not really end with the wedding ceremony.
