>Marriage
Actually the secret untold truth about Marriage was that it was the first ever form of government designed to control groups of people. This is why still in some cultures a man can marry many women, as a form of having indentured servants, not kidding. As time went on, many men found this type of institution unmanageable and sought ways to break free of their own self made bondage. At that point they invented divorce as a precursor to war. As lessons were learned on the battlefield the men gathered in secret societies and swore oaths on how to protect each others freedoms. They put into law, that a man at most could marry only one women and thereby would only need to fight one war in his lifetime. This is why we still have as a tradition, the Father giving the bride away; to this very day.
