Bride price, bride-dowry, bride-wealth, bride service or bride token, is money, property, or other form of wealth paid by a groom or his family to the woman or the family of the woman he will be married to or is just about to marry. Bride dowry is equivalent to dowry paid to the groom in some cultures, or used by the bride to help establish the new household, and dower, which is property settled on the bride herself by the groom at the time of marriage. Some cultures may practice both simultaneously. Many cultures practiced bride dowry prior to existing records.
