In Prussia, men are allowed to form what is called a left-handed marriage, in which the ceremonies are similar to other marriages, excepting that the left hand is used instead of the right. Under these circumstances, neither the wife nor the children assume the name of the husband, or live in his house, or have a legal claim to dower, or succeed to his estate and titles; but they receive what he pleases to give them during his lifetime, and at his death such legacies as are named in his will. These marriages are principally formed by poor nobles, who already have large families. European monarchs are not allowed to marry into any other than royal families; but they sometimes form left-handed marriages with women, who will not consent to be theirs on less honorable terms. By the Prussian laws, a man may be imprisoned, and fined half his fortune, or earnings, if he refuses to marry a woman, whom he has deceived with false promises. If he runs away, the woman may be married to him by proxy, and have a legal claim upon him for the maintenance of herself and child. The laws of most Christian countries do not allow females to dispose of themselves before they are twenty-one years old. If a girl over fourteen marries without the knowledge of her parents, they cannot render the contract void; but if they know of her intention, they have power to forbid the union until she is of age. The consent of both parents is almost universally asked before young people are betrothed; but after they are of age, the opposition of parents cannot prevent marriage, unless the lovers choose to submit, from motives of duty, or filial affection.
