Historian Manolo Florentino refutes the idea that a large part of the Brazilian people is a result of the forced relationship between the rich Portuguese colonizer and the Amerindian or African slaves. According to him, most of the Portuguese settlers in Brazil were poor adventurers from Northern Portugal who immigrated to Brazil alone. Most of them were men (the proportion was eight or nine men for each woman) and then it was natural that they had relationships with the Amerindian or Black women. According to him the mixture of races in Brazil, more than a sexual domination of the rich Portuguese master over the poor slaves, was a mixture between the poor Portuguese settlers with the Amerindian and Black women.
