In the 16th and 17th century, non-Dutch immigrants to Amsterdam were mostly Huguenots, Flemings, Sephardi Jews and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War. The Westphalians came to Amsterdam mostly for economic reasons – their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty percent of them survived the Shoah.
