"As Charles defaulted to his father’s autocratic habits, his throne returned to the vulnerability of the 1640s. On his deathbed in 1685, he showed more concern for his mistresses than his monarchy, and predicted that his brother’s reign would be short. So it proved. Louis’s revocation the same year of the Edict of Nantes (which had guaranteed freedom of worship for Protestants) flooded England with Protestant refugees, and every pulpit resounded to tales of Catholic atrocities. James II's Catholicism was toxic. He had to suppress a rebellion by the Protestant Duke of Monmouth, and began appointing Catholics to senior positions in the army, the church and Oxford University. He used his patronage to pack Parliament with loyal Tories. Even so, with the succession securely Protestant, all might have survived but for a final crisis. In June 1688, James’s wife gave birth to a son, thus removing Mary and William from the succession and substituting a Catholic infant. The battered Restoration compromise was in tatters."
