The Wife of Bath was 12 years old when she first got married, according to the narrative in "The Canterbury Tales.
Meanwhile, William Shakespeare was 18 years old when they got married.
This age difference was not uncommon for the time period, as girls often married at a young age and to older men.
In Geoffrey Chaucer's "The Wife of Bath's Tale," the age of the Wife of Bath when she first married is not explicitly stated. However, the text suggests that she has had multiple marriages throughout her life.
The Wife of Bath proudly proclaims that she has been married five times and mentions that she has had several other relationships outside of marriage as well. Based on these details, it can be inferred that the Wife of Bath would have been quite young when she entered into her first marriage.
