The theme of adultery has been used in a wide range of literature through the ages, and has served as a theme for some notable works such as Anna Karenina and Madame Bovary. As a theme it brings intense emotions into the foreground, and has consequences for all concerned. It also automatically brings its own conflict, between the people concerned and between sexual desires and a sense of loyalty. As marriage and family are often regarded as basis of society, a story of adultery often shows the conflict between social pressure and individual struggle for happiness.
