Whom they marry may be influenced by socially determined rules of incest, prescriptive marriage rules, parental choice and individual desire.In some areas of the world, arranged marriage, child marriage, polygamy, and sometimes forced marriage, may be practiced as a cultural tradition.
Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community, or peers. When a marriage is performed and carried out by a government institution in accordance with the marriage laws of the jurisdiction, without religious content, it is a civil marriage.The act of marriage usually creates normative or legal obligations between the individuals involved, and any offspring they may produce or adopt.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.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. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes.The adjective marīt-us -a, -um meaning matrimonial or nuptial could also be used in the masculine form as a noun for "husband" and in the feminine form for "wife".
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".
For example, the number of marriages in Europe decreased by 30% from 1975 to 2005.
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).
In some areas, child marriages and polygamy may occur in spite of national laws against the practice.
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.
The word "marriage" derives from Middle English mariage, which first appears in 1250–1300 CE.
