Amazing question, if Fluther was global and people were honest.
Keep in mind that in parts of the world today wives can still be women taken as spoils of war.
Mormon founder Joseph Smith was legally married to a 14 yo, something illegal and repugnant today as she is/was under the age of consent.
Today, child marriage is still fairly widespread in developing countries, such as parts of Africa, South Asia, Southeast Asia, West Asia, Latin America, and Oceania.
As @elbanditoroso pointed out, female consent is a fairly modern concept, and spousal consent not only even more modern, but not yet widespread.
