How does Brandon Become a Prince?

Brandon, who is a squire, marries Stella, Princess of Solaria, who will one day rule the kingdom of Solaria. What happens to Brandon title-wise?

In terms of the British monarchy, marrying a princess does make one a prince. It only works the other way around when a prince marries a woman and makes her a princess. If a man marries the Queen of England, assuming that the heir to the previous ruler is female, the lucky man does not become the King. Instead, he is granted a courtesy title that is lower than his wife's.

Marriage is a social union. Remember, marriage was not a union between two equals in the Middle Ages. A man bargained for a woman as much as he would bargain for a good cow. The amount the man agrees to pay for the woman is called the bride price. Along with woman came her dowry, the goods such as money, titles and estates, that she brings to her husband in the marriage. A woman belongs to the man's family. However, Brandon does not become Stella's king simply. Because Stella is a woman, she cannot give Brandon the title of King. King and Queen are the absolute highest titles (King being obviously higher than queen) and those titles can only be given through lineage, not marriage, making them the exception. In this case, Stella's powerful background overrules any inclinations to her lowering herself to Brandon's commoner status. So what would happen to Brandon?

At best, he could become a prince, a duke, or something of the equivalent.

In the case of Bloom and Sky, Sky can give Bloom the title of Queen of Eraklyon, or any title he desires, because he is the King and he is a man.

Also, why do is the British monarchy used as a model to demonstrate the point? The British monarchy is the most well-known example of monarchy that exists today to English-speakers. It makes explaining easier. There is also more accessible, current and accurate information on the details of how a title works compared to monarchies that have been abolished or annexed years ago.
