Marriage, also called matrimony or wedlock, is a culturally and often legally recognised union between people called spouses. It establishes rights and obligations between them, as well as between them and their children (if any), and between them and their in-laws. It is nearly a cultural universal, but the definition of marriage varies between cultures and religions, and over time. Typically, it is an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing sexual activity. A marriage ceremony is called a wedding, while a private marriage is sometimes called an elopement.
Around the world, there has been a general trend towards ensuring equal rights for women and ending discrimination and harassment against couples who are interethnic, interracial, interfaith, interdenominational, interclass, intercommunity, transnational, and same-sex as well as immigrant couples, couples with an immigrant spouse, and other minority couples. Debates persist regarding the legal status of married women, leniency towards violence within marriage, customs such as dowry and bride price, marriageable age, and criminalization of premarital and extramarital sex. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, cultural, economic, political, religious, sexual, and romantic purposes. In some areas of the world, arranged marriage, forced marriage, polygyny marriage, polyandry marriage, group marriage, coverture marriage, child marriage, cousin marriage, sibling marriage, teenage marriage, avunculate marriage, incestuous marriage, and bestiality marriage are practiced and legally permissible, while others areas outlaw them to protect human rights. Female age at marriage has proven to be a strong indicator for female autonomy and is continuously used by economic history research.
