When Marie Thérèse d'Autriche died in 1683, Louis XIV considered marrying a second wife. He decided against this for the reasons that second marriages were usually unhappy and unfortunate for France.
Also, his daughter-in-law, Marie-Anne-Victoire de Bavière had recently given birth to a healthy second son, the Duc d'Anjou (future D. Felipe V of Spain) when he notified the conseil d'etat of the decision (December 1683).
Then in 1690, Marie-Anne-Victoire died (if anyone cane tell me of what, I would appreciate it). And a second marriage was considered for the Dauphin, since Louis XIV was already married (albeit secretly) to Madame Scarron - Françoise d'Aubigné, Marquise de Maintenon.
But what if he had decided, for his "gloire" that he/the dauphin should remarry? Who might he take? And what effects would said marriage have on French foreign policies?
