Incest is human sexual activity between family members or close relatives. This typically includes sexual activity between people in consanguinity, and sometimes those related by lineage. It is condemned and considered immoral in most societies, given that it can lead to an increased risk of genetic disorders in children in case of pregnancy from incestuous intercourse.
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, 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.
Polygamy is the practice of marrying multiple spouses. When a man is married to more than one wife at the same time, it is called polygyny. When a woman is married to more than one husband at the same time, it is called polyandry. In sociobiology and zoology, researchers use polygamy in a broad sense to mean any form of multiple mating.

Clerical celibacy is the requirement in certain religions that some or all members of the clergy be unmarried.

Yibbum is the form of levirate marriage found in Judaism. As specified by Deuteronomy 25:5–10, the brother of a man who died without children is permitted and encouraged to marry the widow. However, if either of the parties refuses to go through with the marriage, both are required to go through a ceremony known as halizah, involving a symbolic act of renunciation of their right to perform this marriage.

The Deceased Wife's Sister's Marriage Act 1907 was an Act of the Parliament of the United Kingdom, allowing a man to marry his dead wife's sister, which had previously been forbidden. This prohibition had derived from a doctrine of canon law whereby those who were connected by marriage were regarded as being related to each other in a way which made marriage between them improper.

In the Sasanian Empire, the state religion Zoroastrianism created the policy that dictated relationships between men and women. Zoroastrianism set what roles women would have, the marriage practices, women's privileges in Sasanian society and influenced Islam when it arose. The moral standards, the structure of life, and the practices of the Sasanian society were found by looking at the religious writing and laws of the time. Women had legal rights, such as to own real estate, but the privileges a woman had depended on what type of wife she was, as did the restriction that were placed on her.
