The aging Louis XIV. does not fall in love with Françoise d'Aubigné, the later Madame de Maintenon and is thus not influenced by her strong anti-Huguenot views, therefore he's not going to issue the Edict of Fontainebleau, revoking the Edict of Nantes, that had granted religious freedom to the very industrious Huguenots, who will ITTL also be allowed to settle in the French North American colonies, where they will enjoy total religious freedom, not just the limited one granted by the Edict of Nantes in the motherland. Both England and Prussia will thus not experience an influx of Huguenot refugees, many of them skilled artisans, to boost their developing industries. The French North American colonies will experience a growth in population at least equal to that of the English ones and will therefore be more able to withstand in the colonial wars of the 18th century.
Being influenced by enlightened Huguenot advisors, Louis XV. and Louis XVI. will allow gradual reforms, thus avoiding the devastating results of the French Revolution. France becomes the first and most industrialised country in the world, enjoying sound public finances, that allow her to entertain the largest fleet in world. By 1800, Britain has lost its last colonies in India to France. Shortly thereafter, a young and dynamic general named Léon Bonaparte conquers the entire North African shore, from Marocco to Egypt for France, within less than a year, the French start the construction of a canal at the isthmus of Suez to be able to reach their ever growing Indian Empire, which by then incompasses Burma and Indochina as well, and their prospering colonies in Australie and Nouvelle-Zélande significantly faster.
