An analysis of marriage patterns in nineteenth-century Cuba, a society with a large black population the majority of which was held in slavery but which also included considerable numbers of freedmen. Dr Martinez-Alier uses as her main source of evidence the records in Havana of administrative and judicial proceedings of cases in which parents opposed a marriage, of cases involving elopement, and of cases of interracial marriage. Dr Martinez-Alier develops a model of the relation between sexual values and social inequality. She considers the importance of the value of virginity in supporting the hierarchy of Cuban society, based on ascription rather than achievement. As a consequence of the high evaluation of virginity, elopement was often a successful means of overcoming parental dissent to an unequal marriage. However, in cases of interracial elopement, the seduced coloured woman had little chance of redress through marriage. In this battle of the sexes and the races, the free coloured women and men played roles and acquired values which explain why matrifocality became characteristic of black free families.
