Among aristocratic families in those days, love was seldom, if ever, a valid reason for couples to get married. Noble marriages were strategic alliances between powerful families, a way of maintaining or improving their social standing. And this prevailing attitude is one clearly shared by Lady Capulet, as we can see in act 1, scene 3 of Romeo and Juliet.

Lady Capulet is determined that her daughter shall marry the dashing and noble Count Paris, scion of one the best families in Verona. Although Lady Capulet draws Juliet's attention to Paris's good looks, she also reveals the most important of his characteristics—his high social standing:

That book in many's eyes doth share the glory
That in gold clasps locks in the golden story.
So shall you share all that he doth possess
By having him, making yourself no less. (I, iii, 93-96)

In other words, if Juliet marries Paris she will not just maintain the same social status that she has now, but she will actually improve it. As Paris's bride she will become widely admired and share in his glory. The reference to Paris's glory is related to his family's good name. His family obviously has a very high reputation, and Juliet's parents are keen that their daughter should bask in the reflected glory of that name, which is why they want her to marry Paris.

As was common at the time, the prospective bride's personal feelings don't enter into it at all. She is nothing more than a pawn in a proposed strategic alliance between two powerful families.
