In 1469, a marriage took place that would reshape the future of Spain.Ferdinand of Aragon and Isabella of Castile came from two powerful kingdoms.Isabella, the heir to Castile, chose Ferdinand over other suitors, recognizing the strategic advantage of uniting their kingdoms.Their marriage agreement was revolutionary for its time, establishing a unique power-sharing arrangement.The agreement established them as equal co-rulers, each maintaining sovereign power over their respective kingdoms.This created a complex but effective system of shared governance.This personal union brought numerous advantages to both kingdoms, laying the groundwork for Spain's future unification.This marriage would prove to be the foundation for the creation of modern Spain.The Granada War began in 1482, as Ferdinand and Isabella launched their final campaign of the Reconquista.The Christian armies employed sophisticated siege tactics, including year-round campaigns and artillery bombardment.Major cities fell one by one. Ronda surrendered in 1485, followed by the crucial port city of Málaga in 1487.By 1489, Almería had surrendered, leaving Granada increasingly isolated.The siege of Granada itself lasted from 1491 to early 1492. Ferdinand and Isabella built a whole new city, Santa Fe, to maintain their siege through the winter.On January 2, 1492, Granada's last Muslim ruler, Boabdil, surrendered the keys of the Alhambra palace to the Catholic Monarchs.The fall of Granada marked the end of nearly eight centuries of Muslim presence in Iberia, completing the Christian Reconquista.This victory established a unified Spanish monarchy that would soon become one of Europe's most powerful nations.
