Very little research has been done specifically on the condition of the Gypsy slaves in Wallachia. Most general histories ignore them, and few contemporary observers studied them. This is just one more sign of their discrimination and neglect. This study draws on the exhaustive nominal lists of the Romani population from the database MapRom which draws on the first preserved count of the population of Danubian principalities (1838). Many aspects of the rob-slave condition have been analysed, the household size, the socio-professional and juridical categories and the Gypsy owners, the degree to which the Gypsies in Wallachia were integrated into the majority population and the ethnic attitudes of the surrounding population, and a case study of formation of a Gypsy settlement.
