Harem former times, some harems were guarded by eunuchs (castrated men) who were allowed inside. 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. Although the institution has experienced a sharp decline in the modern era, seclusion of women is still practiced in some parts of the world, such as rural Afghanistan and conservative states of the Gulf region.
Who is a Jew? Jews see being Jewish as predominantly a matter of ancestry and culture, rather than religion. The definition of who is a Jew varies according to whether it is being considered by Jews on the basis of religious law and tradition or self-identification, or by non-Jews for other reasons, sometimes for prejudicial purposes. Because Jewish identity can include characteristics of an ethnicity, a religion, or peoplehood, the definition depends on either traditional or newer interpretations of Jewish law and custom. Israel's Law of Return stipulates that a Jew is someone with a Jewish mother or someone who has converted to Judaism
