Marriage (also called matrimony or wedlock) is a social union or legal contract between people called spouses that creates kinship. The definition of marriage varies according to different cultures, but is usually an institution in which interpersonal relationships, usually intimate and sexual, are acknowledged. Such a union is often formalized via a wedding ceremony. In terms of legal recognition, most sovereign states and other jurisdictions limit marriage to two persons of opposite sex or gender in the gender binary, and some of these allow polygynous marriage. In the 21st century, 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. These might include arranged marriages, family obligations, the legal establishment of a nuclear family unit, the legal protection of children and public declaration of commitment. 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.[3] Surveys show that people who are married are more likely to be happy than those who are not married.
