Introduction
Marriage (also called matrimony or wedlock) is a social union or legal contract between people called spouses that establishes rights and obligations between the spouses, between the spouses and their children, and between the spouses and their in-laws. The definition of marriage varies according to different cultures, but it is principally an institution in which interpersonal relationships, usually intimate and sexual, are acknowledged. When defined broadly, marriage is considered a cultural universal. In many cultures, marriage is formalized via a wedding ceremony. In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to opposite sex couples or two persons of opposite gender in the gender binary, and some of these allow polygynous marriage. Since 2000, several countries and some other jurisdictions have legalized same-sex marriage. In some cultures, marriage is recommended or compulsory before pursuing any sexual activity.
People marry for many reasons, including: legal, social, libidinal, emotional, financial, spiritual, and religious. Marriages can be performed in a secular civil ceremony or in a religious setting. The act of marriage usually creates normative or legal obligations between the individuals involved. Some cultures allow the dissolution of marriage through divorce or annulment. Polygamous marriages may also occur in spite of national laws.
Marriage can be recognized by a state, an organization, a religious authority, a tribal group, a local community or peers. It is often viewed as a contract. Civil marriage is the legal concept of marriage as a governmental institution irrespective of religious affiliation, in accordance with marriage laws of the jurisdiction. Forced marriages are illegal in some jurisdictions.
History of marriage
Although the institution of marriage pre-dates reliable recorded history, many cultures have legends concerning the origins of marriage. The way in which a marriage is conducted and its rules and ramifications has changed over time, as has the institution itself, depending on the culture or demographic of the time. Various cultures have had their own theories on the origin of marriage. One example may lie in a man’s need for assurance as to paternity of his children. He might therefore be willing to pay a bride price or provide for a woman in exchange for exclusive sexual access.
Legitimacy is the consequence of this transaction rather than its motivation. In Comanche society, married women work harder, lose sexual freedom, and do not seem to obtain any benefit from marriage. But nubile women are a source of jealousy and strife in the tribe, so they are given little choice other than to get married. “In almost all societies, access to women is institutionalized in some way so as to moderate the intensity of this competition.” Forms of group marriage which involve more than one member of each sex, and therefore are not either polygyny or polyandry, have existed in history. However, these forms of marriage are extremely rare. Of the 250 societies reported by the American anthropologist George P. Murdock in 1949, only the Caingang of Brazil had any group marriages at all.
Various marriage practices have existed throughout the world. In some societies an individual is limited to being in one such couple at a time (monogamy), while other cultures allow a male to have more than one wife (polygyny) or, less commonly, a female to have more than one husband (polyandry). Some societies also allow marriage between two males or two females. Societies frequently have other restrictions on marriage based on the ages of the participants, pre-existing kinship, and membership in religious or other social groups.
Rights and obligations
A marriage bestows rights and obligations on the married parties, and sometimes on relatives as well, being the sole mechanism for the creation of affinal ties (in-laws). These may include, depending on jurisdiction:
Giving a husband/wife or his/her family control over a spouse’s sexual services, labor, and property.
Giving a husband/wife responsibility for a spouse’s debts.
Giving a husband/wife visitation rights when his/her spouse is incarcerated or hospitalized.
Giving a husband/wife control over his/her spouse’s affairs when the spouse is incapacitated.
Establishing the second legal guardian of a parent’s child.
Establishing a joint fund of property for the benefit of children.
Establishing a relationship between the families of the spouses.
