The Royal Exchange

In 1721, on the pretext of wishing to consolidate the peace, Philip of Orleans, then regent of France, proposes to Philip V, King of Spain, a marriage between the heir to the French throne, Louis XV, aged 11, and the very young infanta of Spain, Anna Maria Victoria, aged 4.And he does not stop there: He proposes to give his daughter, Miss de Montpensier, aged 12, as wife to the Prince of Asturias, heir to the Spanish throne, to strengthen his positions and consolidate the end of the conflict between the two kingdoms.The proposals are accepted with enthusiasm in Madrid and things are put rapidly into place.The change of princesses takes place at the beginning of 1722, with great pomp and ceremony, on a small island in the middle of the Bidassoa, the river that serves as border between the two countries.
