Conversely, such practices may be outlawed and penalized in parts of the world out of concerns of the infringement of women's rights, or the infringement of children's rights (both female and male children), and because of international law.
In developed parts of the world, there has been a general trend towards ensuring equal rights within marriage for women and legally recognizing the marriages of interfaith, interracial, and same-sex couples.
The related word "matrimony" derives from the Old French word matremoine, which appears around 1300 CE and ultimately derives from Latin mātrimōnium, which combines the two concepts: mater meaning "mother" and the suffix -monium signifying "action, state, or condition".
In The History of Human Marriage (1922), Edvard Westermarck defined marriage as "a more or less durable connection between male and female lasting beyond the mere act of propagation till after the birth of the offspring." In The Future of Marriage in Western Civilization (1936), he rejected his earlier definition, instead provisionally defining marriage as "a relation of one or more men to one or more women that is recognized by custom or law".
The anthropological handbook Notes and Queries (1951) defined marriage as "a union between a man and a woman such that children born to the woman are the recognized legitimate offspring of both partners." In recognition of a practice by the Nuer people of Sudan allowing women to act as a husband in certain circumstances (the ghost marriage), Kathleen Gough suggested modifying this to "a woman and one or more other persons." In an analysis of marriage among the Nayar, a polyandrous society in India, Gough found that the group lacked a husband role in the conventional sense; that unitary role in the west was divided between a non-resident "social father" of the woman's children, and her lovers who were the actual procreators.
None of these men had legal rights to the woman's child.
Since the late twentieth century, major social changes in Western countries have led to changes in the demographics of marriage, with the age of first marriage increasing, fewer people marrying, and more couples choosing to cohabit rather than marry.
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.
Marriage, also called matrimony or wedlock, is a socially or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity (in-laws and other family through marriage).
The definition of marriage varies around the world not only between cultures and between religions, but also throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but typically it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned.
Historically, in most cultures, married women had very few rights of their own, being considered, along with the family's children, the property of the husband; as such, they could not own or inherit property, or represent themselves legally (see for example coverture).
