Ibo highly value family and practice polygamy, taking multiple wives who become mothers of his children. They raise the children separately, with each wife's household acting somewhat independently of the other but collaborating to form a compound.
then
Ibo are forbidden to marry people who share blood through matriarchal or patriarchal lines
Because of that, they often had to marry people from other villages
Men had as many wives as they could support, and more wives were a sign of status
Women and men alike can marry women, so long as they can pay the bride price
Beating wives was not considered a crime (with the exception of holidays like the Week of Peace)
Each household consited of a "large compound enclosed by a thick wall of red earth" (Achebe 11). The man had his own obi, or hut, and each wife had her own hut to live in with her children
Fathers passed down possessions, like barns, to their children. If there were no barns to inherit, as in Okonkwo's case in Things Fall Apart, the son can share-crop
A man was "judged according to his worth and not according to the worth of his father" (Achebe 5)
Wives are expected to have children, and it is considered a woman's crowning achievement
Wives were also expected to prepare food for the husband
The first wife of a man was the "highest" in the power/social ranking of wives
now
Compounds still exist, but now are made of cement brick houses instead of mud, due to Western influence and population density
Inheritance is mostly handed to the first son, who then is given charge of his siblings. There are complications, such as if the first son is a minor, but there are several ways to work around it, one of which would be to have a paternal uncle take charge
Some Ibo familial traditions remain a part of the culture, such as polygamy and bride prices. However, Christian/Judeo-Christian marriage has greatly impacted the Ibo's views on polygamy, and amongst white-collar Ibo the trend is towards a nuclear family with one residence
