トラスタマラ家
With the selection of a younger prince of the Castilian Royal House of Trastámara, the Aragonese Crown became increasingly drawn into the sphere of influence of the more powerful Castile. About 50 years after the Compromise, with the marriage of Ferdinand I's grandson Ferdinand II to Queen Isabella of Castile, Aragon became the junior partner in a dynastic union that would become the modern Spanish state.
