Biography
Miguel da Paz entered the world as the most coveted child in Europe. Born in 1498 to King Manuel I of Portugal and Isabella of Aragon, he was the living, breathing symbol of a grand unification. Through his parents, he was the heir to the crowns of Portugal, Castile, and Aragon—a potential ruler of a single, unimaginably vast Iberian empire that would have encompassed global exploration and immense wealth. His nursery was a diplomatic hub, and his health was a matter of state. For two years, this tiny boy held the future of continents in his grasp. His sudden death in 1500, likely from illness, shattered the dream. The crowns fractured, passing to other lines, and the separate paths of Spain and Portugal were cemented. His story is one of colossal historical might-have-beens, where the fate of empires hinged on the life of a toddler.
