Netherlands

William Penn, the Quaker founder of Pennsylvania, who had a Dutch mother, visited the Netherlands in 1671 and saw, first hand, the persecution of the Emden Quakers. He returned in 1677 with George Fox and Robert Barclay and at Walta Castle, their religious community at Wieuwerd in Friesland, he unsuccessfully tried to convert the similarly minded Labadists to Quakerism. They also journeyed on the Rhine to Frankfurt, accompanied by the Amsterdam Quaker Jan Claus who translated for them. His brother, Jacob Claus, had Quaker books translated and published in Dutch and he also produced a map of Philadelphia, the capital of Penn's Holy Experiment.
