How do you become a baroness?

Answer 1

These days, there are not that many of them any more. It is usually a hereditary title (you have to be born into it); a man is a baron, while a woman is a baroness. The title itself goes back to the days of feudalism. Today, it is considered a lower-level of nobility, ranking below a viscount and countess in countries that still have such titles. There are some people who have purchased an honorary version of this title, but they are not considered members of the nobility.

Answer 2

In most societies, you would have to be born into a certain family to become a baron. So, really, you would have to inherit it. You couldn't just become a baron.
