The culturally specific theme is the tragic division of families in the US Civil War.
The theme is culturally specific because it is focused on a single topic that can be identified and there is no way to misinterpret it: the US Civil War. It is not an ambiguous theme, is very specific. It had a central topic, a date, a moment in time and a place. And it also has a social structure, the family, that was tremendously affected.
