House of Braganza Braganza has allegedly suffered from the Curse of the Braganzas (Portuguese: "Maldição dos Braganças"). For supposedly mistreating a Franciscan friar, a curse was purportedly placed on King João IV of Portugal, stating that never again would a first-born male of the Braganza Dynasty would live long enough to succeed to the throne.
