Human beings are social animals: they meet in private and in public, they have more or less close contacts with one another, and they enter into love relationships. As far as these are concerned it is often not a case of romantic love stories but of involuntary liaisons.
Where did encounters between people from different cultures and social classes take place? Where did emperor and people meet? Who was allowed to love whom? Why did people who scarcely knew each other marry while they were still children?
