Biography
Ferdinand of Antequera was a king who ruled by compromise and calculation. In the early 15th century, the Crown of Aragon was plunged into a crisis with no clear heir. Ferdinand, a Castilian prince and regent of Castile, emerged as the chosen candidate through the diplomatic Compromise of Caspe in 1412. His election was a political masterstroke, ending a bitter interregnum and uniting the crowns of Aragon and Sicily with the influence of Castile. His short reign, just four years, was defined by a push for internal stability and a renewed focus on Mediterranean affairs, challenging Genoese power. While his time on the throne was brief, his selection established the Trastámara dynasty in Aragon, setting the stage for the future marriage of Ferdinand and Isabella and the unification of Spain.
