Final answer:
The Reconquista was completed in 1492 with the fall of Granada, ending nearly eight centuries of Muslim control in the Iberian Peninsula.
Step-by-step explanation:
Christians were able to complete their Reconquista of the Iberian Peninsula in the year 1492. This marked the end of the nearly eight-hundred-year struggle to reclaim the territory from Muslim rule, which had begun with the Muslim conquests in 711.
The fall of Granada to the Catholic Monarchs, Ferdinand and Isabella, symbolized the end of this historic period, severing the long-standing connections between southern Spain and the Islamic centers of civilization in the East. This conclusion of the Reconquista coincided with another significant event in history: Christopher Columbus's first voyage across the Atlantic, which led to the European discovery and subsequent colonization of the Americas.
