Treaty of Fontainebleau (1745)
The Treaty of Fontainebleau was a 1745 treaty in which France committed itself to support the Jacobite rising of 1745.
It was signed on October 24, 1745, in Fontainebleau, France, between Louis XV of France and the pretender to the thrones of Great Britain and Ireland, James Francis Edward Stuart. It was signed for France by the Marquis d'Argenson and for James's son, Charles Edward Stuart, "Prince Regent of Scotland", by Colonel Daniel O'Brien.
Based on the terms of the accord, Louis recognized James as the rightful King of Scotland and promised to support him, militarily if necessary, in a claim on the throne of England, if it became apparent that the English people supported a Stuart restoration. Under the treaty, France offered "all practical assistance" to the Jacobite cause.
In the event, the rising collapsed. Although preparations were made at Dunkirk for a French force to invade England, it never set sail.
