Why didn't princes kiss in ancient times?

In fact, this is an exchange of political relations to some extent. Generally speaking, marriage is mostly for the purpose of alliance, trade and truce, and because in various alliance agreements, the relationship between marriage and marriage will be stronger, because the two sides become relatives, so some things will give some face.

Among them, kissing the princess is a very beneficial way to win the battle. For example, I want to take your land, but I will definitely be beaten if I rob it directly, so I will marry my sister to your family, so that the children born to her will have the inheritance right of your family, and then I will take your land in a justified way.

But if the princess is replaced by a prince, the relationship will be more complicated. First of all, the prince kissed him like never before, and even some of them are what we are talking about now. Secondly, the prince himself has the right to inherit his country. He went to kiss, so who owns this right? Moreover, most princes have political education since childhood, but princesses don't, so princes are in danger of intervening in politics, and no one wants to bring home the threat of overthrowing the dynasty.

Finally, the relationship between men and women is superior. It was very wronged to marry a foreign princess in order to seek foreign aid. How can you send the prince out? Even if the emperor doesn't like the prince, he just wants him to check in early, and it is impossible to transfer his son-in-law to someone else as a door-to-door son-in-law This is not only a feeling of transferring real power to others, but also more likely to lead to war between the two countries.
