The rationale behind this practice is that a child's parents can arrange a sensible match with the parents of a child from a suitable family, thus securing the child's future at a young age. Many people who have been married this way do grow to love and cherish their spouses after the marriage. It is thought by adherents that romantic love is not a suitable foundation upon which to build a marriage and a family.
Families are able to cement political and/or financial ties by having children intermarry. The betrothal is considered a binding contract upon the families and the children. The breaking of a betrothal can have serious consequences for both the families and the children themselves. The practice of child marriage has continued to fall further and further out of favor in modern times; however, it is still practiced by some sub-cultures.
