Marriage

Marriage was a socially or ritually recognized union or legal contract between spouses that established rights and obligations between them, between them and their children, and between them and their in-laws. The definition of marriage varied according to different cultures, but was principally an institution in which interpersonal relationships, usually sexual, were acknowledged. In some cultures, marriage was recommended or considered to be compulsory before pursuing any sexual activity. When defined broadly, marriage was considered a cultural universal.
