During the King’s stay at Hanover an important treaty was concluded with France. The Jacobite rising had made it desirable that James should quit Lorraine, and the Regent of France was willing to enter into an alliance with England. A treaty was signed between England and France on November 28th, 1716. The Dutch subsequently entered into this alliance, which became known as the Triple Alliance. In consequence of this treaty James was forced to quit Lorraine, and went to Italy, where he resided, sometimes at Rome, and sometimes at Urbino. Soon after his arrival at Rome he contracted a marriage by proxy with the Princess Clementina, a granddaughter of John Sobieski, the late King of Poland, a princess remarkable for her beauty and grace. The Princess set out for Italy, where the full marriage was to take place; but the British Government, having knowledge of her movements, meanly prevailed on the Emperor of Austria to detain her at Innsbrück. She was kept there nearly three years, and James was left waiting for his bride. [Illustration: LEIBNIZHAUS, HANOVER.

It was the King’s intention to open Parliament immediately, and to settle scores with the Prince of Wales, who now retired into comparatively private life. But his mind was diverted for the moment by the discovery of a fresh Jacobite plot for the invasion of Scotland by twelve thousand Swedish soldiers. The affair was planned by Gortz, the Swedish Prime Minister, and the headquarters of the plot were found to be at the Swedish legation in London. Gyllenborg, the Swedish envoy, was arrested, and his papers seized, despite his protest that the law of nations was being violated. The King of Sweden, Charles the Twelfth, was communicated with, but as he would neither avow nor disavow Gortz, the envoy was kept in durance for a while, and then sent across the Channel, and set at liberty in Holland.
