WI Charles II of Spain had lived just as long as his brother Felipe Prospero (04 years) and died in 1665, a month later his father's death? Philip IV would have left just two surving daughters: Maria Teresa, who was already married to Louis XIV of France and had a male son, Louis; and Margarita, who was promised to the Emperor Leopold I (but not married yet, since she only married him in December 1666). Would we see an earlier War of Spanish Succession? And how could it go?
