While Western ways of courtship and marriage are not unheard of, the power of traditional values and the strong influence of the family mean that traditional ways are usually followed, even in the cities and among the elite. According to old customs, women did not have much choice of whom they married, though the numbers of arranged marriages are declining. It is also not uncommon for women to marry in their teens, often to a much older man. In instances where there are already one or more wives, it is the first wife's responsibility to look after the newest wife and help her integrate into the family. Many Nigerian ethnic groups follow the practice of offering a bride price for an intended wife. Unlike a dowry, in which the woman would bring something of material value to the marriage, a bride price is some form of compensation the husband must pay before he can marry a wife. A bride price can take the form of money, cattle, wine, or other valuable goods paid to the woman's family, but it also can take a more subtle form. Men might contribute money to the education of an intended wife or help to establish her in a small-scale business or agricultural endeavor. This form of bride price is often incorporated as part of the wooing process. While women who leave their husbands will be welcomed back into their families, they often need a justification for breaking the marriage. If the husband is seen as having treated his wife well, he can expect to have the bride price repaid. Though customs vary from group to group, traditional weddings are often full of dancing and lively music. There is also lots of excitement and cultural displays. For example, the Yoruba have a practice in which the bride and two or three other women come out covered from head to toe in a white shroud. It is the groom's job to identify his wife from among the shrouded women to show how well he knows his wife. Divorce is quite common in Nigeria. Marriage is more of a social contract made to ensure the continuation of family lines rather than a union based on love and emotional connections. It is not uncommon for a husband and wife to live in separate homes and to be extremely independent of one another. In most ethnic groups, either the man or the woman can end the marriage. If the woman leaves her husband, she will often be taken as a second or third wife of another man. If this is the case, the new husband is responsible for repaying the bride price to the former husband. Children of a divorced woman are normally accepted into the new family as well, without any problems. Domestic Unit. The majority of Nigerian families are very large by Western standards. Many Nigerian men take more than one wife. In some ethnic groups, the greater the number of children, the greater a man's standing in the eyes of his peers. Family units of ten or more are not uncommon. In a polygamous family, each wife is responsible for feeding and caring for her own children, though the wives often help each other when needed. The wives also will take turns feeding their husband so that the cost of his food is spread equally between or among the wives. Husbands are the authority figures in the household, and many are not used to their ideas or wishes being challenged. In most Nigerian cultures, the father has his crops to tend to, while his wives will have their own jobs, whether they be tending the family garden, processing palm oil, or selling vegetables in the local market. Children may attend school. When they return home, the older boys will help their father with his work, while the girls and younger boys will go to their mothers.
