What is the difference between a wife and a concubine?
It varies from culture to culture. First of all the wife is the legal first lady of the house. Her children are THE heirs. There may be secondary wives, whose children also may inherit part of the father’s estate/wealth. A concubine, however, is normally lower status than a wife. She may be a captive or have been sold into this status by her poor parents. Her children generally do not have the same rights as those of the wives, although the father may or may not provide for them.
