Rhys' success in the novel however, is based on her intimate knowledge of the social relations in Dominica in the late nineteenth century.
The novel also represents the author's imaginative triumph in her treatment of themes related to oppression, racism, inequality and finally triumph over adversity. Jean Rhys' Wide Sargasso Sea marks the culmination of her preoccupation with Dominica and the interweaving of the island's history into her works of fiction.
