Harem (Arabic: حريم ḥarīm, "a sacred inviolable place; harem; female members of the family"), also known as zenana in South Asia, properly refers to domestic spaces that are reserved for the women of the house in a Muslim family and are inaccessible to adult males except for close relations. Similar institutions have been common in other Mediterranean and Middle Eastern civilizations, especially among royal and upper-class families, and the term is sometimes used in non-Islamic contexts. The structure of the harem and the extent of monogamy or polygamy has varied depending on the family's personalities, socio-economic status, and local customs. This private space has been traditionally understood as serving the purposes of maintaining the modesty, privilege, and protection of women. A harem may house a man's wife—or wives and concubines, as in royal harems of the past—their pre-pubescent male children, unmarried daughters, female domestic workers, and other unmarried female relatives. In former times, some harems were guarded by eunuchs who were allowed inside. Although the institution has experienced a decline in the modern era, the spatial seclusion of female family members from male visitors to the house is still practiced in many parts of the Muslim world. In the West, Orientalist imaginary conceptions of the harem, as a personal brothel where numerous women lounged in suggestive poses, have influenced culture and to certain extent relationship with Islamic societies through many paintings, music, stage productions, films and literary works, and the word has become particularly associated with polygyny and large royal harems.
The word has been recorded in the English language since early 17th century. It comes from the Arabic ḥarīm, which can mean "a sacred inviolable place", "harem" or "female members of the family". The triliteral Ḥ-R-M appears in other terms related the notion of interdiction such as haram (forbidden), mahram (unmarriageable relative), ihram (a pilgrim's state of ritual consecration during the Hajj) and al-Ḥaram al-Šarīf ("the noble sanctuary", which can refer to the Temple Mount or the sanctuary of Mecca).
