Some countries do not recognize locally performed religious marriage on its own, and require a separate civil marriage for official purposes.
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.
These changes included giving wives legal identities of their own, abolishing the right of husbands to physically discipline their wives, giving wives property rights, liberalizing divorce laws, providing wives with reproductive rights of their own, and requiring a wife's consent when sexual relations occur.
These changes have occurred primarily in Western countries.
In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity.
