The act of marriage usually creates normative or legal obligations between the individuals involved, and any offspring they may produce.
In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite-sex couples and a diminishing number of these permit polygyny, child marriages, and forced marriages.
Over the twentieth century, a growing number of countries and other jurisdictions have lifted bans on and have established legal recognition for interracial marriage, interfaith marriage, and most recently, same-sex marriage.
In some areas of the world, arranged marriage, child marriage, polygamy, and sometimes forced marriage, may be practiced as a cultural tradition.
Conversely, such practices may be outlawed and penalized in parts of the world out of concerns for women's rights and because of international law.
In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity.
When defined broadly, marriage is considered a cultural universal.
