Evidence from the Jewish cemetery of Oudekerk and in the local Sephardic records show people of African descent were part of the Portuguese Jewish community. Some were slaves, others as servants and some were free. All were Jews. But none were given the dignity they deserved.
If it seems strange that a group of Jews from Portugal wound up in Amsterdam in the 1600s, it helps to understand what started in Spain a little more than a hundred years earlier. In 1478, a Dominican friar convinced Queen Isabella of Spain that Jews who had converted to Christianity were still secretly practicing their old beliefs. The queen and King Ferdinand petitioned Pope Sixtus IV to start an inquisition.
