From the earliest days of its history, Brazil has been a favoured ‘laboratory’ for ethnic, cultural and religious hybridization. The absence or scarcity of white women and the temptations of sexual exoticism drove the Portuguese discoverers, and with them sailors from Normandy, Brittany and Poitou, to have relations with Indian women they chanced to meet, thus creating a race of coloured people, oddly called mamelucos, later cabocles (of mixed white and Indian ethnicity). Afterwards, the very substantial recourse to the Negro slave trade and to manpower of African slave origin because of the requirements of the sugarcane economy (which remained predominant for a long time, especially in the Nordeste region of Bahia and Pernambuco), as well as the numerical imbalance of the sexes, characterized by a great predominance of men, popularized concubinage - all the more so because the Catholic Church was extremely reluctant to sanction interethnic unions with the sacrament of marriage. The Jesuits even recommended the despatch of white prostitutes or women condemned by common law (degredadas), for whom Brazil would furnish the opportunity for redemption, in order to avoid or reduce the number of unions of this kind. Thus, concubinage was the most common vehicle of miscegenation in Brazil.
