The purpose of this research is to study the changing social status and role of Thai women in thai novels between 1920s - 1970s. Until the reign of Rama IV of Rattanakosin era, daughters were brought up to be good wives and mothers, strictly educated by their own parents. Daughters of the poor could be sold legally by their parents. Since 1860s the status of them was better because they had better education. Having the modern(european) education, this consciousness of women of daughters and wives have been changed, especially the consciousness on their rights and duties and social roles as a woman. They had self-confidence and had their own way of life. They dared to break some old tradition such as the arranged marriage by their parents without their consents, khlum thung chon. Then worked outside as a school teacher, secretary, writer, and other part-time works as money lender or land broker. Due to modernization and the founded democratic government in Thailand, women had changed to share activities in politics, too.
