2nd Answer:
I have seen or heard many times that medieval people married young, and the marriages were arranged. When I decided to do a little research on the subject, what I found is that this was the case in some marriages of members of royal families, where international treaties were at stake. For most people, however, this is not how it was done. The materials I have seen written by historians indicate that most marriages were delayed until proper dowries could be accumulated. In some cultures, such as among the Visigoths, this was required by law, and in others, it was custom. But the effect was that women usually got married between the ages of 20 and 25.
The Catholic Church discouraged early marriages and discouraged marriage agreements. One of the grounds for annulment was that one of the partners was too young or was required to marry according to some arrangement.
