After the fall of Clarendon a different policy was attempted. The rigid exclusiveness of the Puritans had bequeathed one sinister vice to the English people. They were complacent in their insularity, and had a prejudice against the foreigner. It had been directed against Spain, for the sake of Plate fleets to seize and coasts to pillage; and now it was strongest against the Dutch, who were dangerous rivals by sea, both in peace and war. It was least, at that time, against France, whose great statesman, Mazarin, had made terms with the Republic, and retained the friendship of the restored king. A trivial dispute on the Guinea Coast was fanned into a quarrel by the Duke of York, who was a sailor, and who hoped to strengthen his position at home by his professional skill, in which he only partially succeeded. This is the war that terminated in the memorable change of front of the Triple Alliance, uniting the Dutch, the English, and the Swedes against France. It was a popular but totally ineffective measure; and in 1669 England abandoned her allies and went over to France. Lewis XIV accomplished this important diplomatic success by the Treaty of Dover, the first in the process of events that overthrew the Stuart monarchy, and brought in the modern type of Constitution. Soon after his return to England, Charles opened negotiations with Rome, which were carried on through one of his sons, born before Monmouth, who became a Jesuit; and he vainly endeavoured to obtain supplies from Alexander VII. Later on, he sought them in France. It was impossible, he said, to restore the royal authority unless it was done through the restoration of Catholicism. That could be secured, if Lewis would make him independent of the House of Commons. The scheme was prepared in January 1669, Arlington consenting, for a bribe of L12,000. It was decided to restore the Catholic Church in England by such a display of force as should be sufficient to raise the crown above the restraints of parliament. In execution of the design Lewis advanced L80,000, and undertook, in case of resistance, to furnish a force of 6000 men, to be a French garrison in England, for the repression of Protestants. The sum was much less than Charles demanded, for the object of the French king was not to strengthen, but to weaken him. The second point in the Treaty was that England engaged to support France in any claims she might have upon Spain. Lastly, England was to help her ally against Holland, in return for further payments and the annexation of Walcheren. But it was agreed to postpone the Dutch war until the year 1672. That is the solid substance of the phantom which is called the Popish Plot. It was, in reality, a plot, under cover of Catholicism, to introduce absolute monarchy, and to make England a dependency of France, not only by the acceptance of French money, but by submission to a French army. Charles I and his ministers had gone to the block for less than this.
