Classism, and the problems it brings, is a major theme throughout the series. The love of children and grandchildren, romance, marriages of convenience, lying, greed, and other themes are also present.
There are a few violent scenes, including a woman who dies in childbirth covered in blood, and the quick smashing of glass on a man’s head (causing some small face wounds). There are also descriptions of the dead after the Battle of Waterloo.
There’s some strong innuendo, including a scene of people getting out of bed. Some women are fooled into having sex with men, while others actively seek extramarital affairs.
Characters are shown drinking over meals, at clubs, while gambling, etc. as was common for the time.
