In Europe, the United States, and other places in the developed world, beginning in the late 19th century and lasting through the 21st century, marriage has undergone gradual legal changes, aimed at improving the rights of the wife.
None of these men had legal rights to the woman's child.
This forced Gough to disregard sexual access as a key element of marriage and to define it in terms of legitimacy of offspring alone: marriage is "a relationship established between a woman and one or more other persons, which provides a child born to the woman under circumstances not prohibited by the rules of relationship, is accorded full birth-status rights common to normal members of his society or social stratum." Economic anthropologist Duran Bell has criticized the legitimacy-based definition on the basis that some societies do not require marriage for legitimacy.
Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law.
In countries governed by a mixed secular-religious legal system, such as in Lebanon and Israel, locally performed civil marriage also does not exist within the country, preventing interfaith and various other marriages contradicting religious laws from being entered into in the country, however, civil marriages performed abroad are recognized by the state even if they conflict with religious laws (in the case of recognition of marriage in Israel, this includes recognition of not only interfaith civil marriages performed abroad, but also overseas same-sex civil marriages).
For example, the number of marriages in Europe decreased by 30% from 1975 to 2005.
