There were many reasons a marriage could not take place, and strict rules for whether or not a divorce was allowed.
Despite the differences in various aspects of marriage, the marriage ceremony has stayed rather similar over the years.
The arrangement of marriage was done by the children's parents.
In the Middle Ages children were married at a young age.
If the boy or the girl had taken a monastic or religious vow the marriage was also prohibited.
Sometimes widows or widowers took vows of celibacy on the death of their spouse, and later regretted doing so when they could not remarry.
The notice stated who was to be married, and if anyone knew any reasons the two could not marry they were to come forward with the reason.
