As the title says. In 1572, just two months after the Saint Bartholomew's Massacre, the wife of Charles IX of France - Elisabeth of Austria - gave birth to his only daughter - Marie Elisabeth of Valois. However, the queen never gave birth again, and when Charles dies two years later his brother Henry became king of France. But he would also die childless, starting the succession crisis that increased the French Religious Wars (as the Catholic League didn't accept the Protestant Henry III of Navarre as king).
Now, WI Elisabeth had given birth to son instead, who is also luckier than Marie and doesn't die young? How could it affect the religious conflict in France? Also, given that now Henry doesn't have a throne in France, would he stay as king of Poland?
