Reconquista in AP World History: Modern

The Reconquista was the series of military campaigns, stretching from the 700s to 1492, in which Christian kingdoms of the Iberian Peninsula took land back from Muslim rulers. It ended when Ferdinand of Aragon and Isabella of Castile captured Granada, the last Muslim-ruled state in Iberia, in January 1492. The same year, Spain expelled its Jews and sponsored Columbus's first voyage.

From 711 to the mid-1200s: al-Andalus shrinks

Muslim armies crossed from North Africa in 711 and took most of the peninsula within a few years. Muslim-ruled Iberia was called al-Andalus. A small Christian kingdom, Asturias, held out in the northern mountains, and later kingdoms like Castile, Aragon, Navarre, and Portugal grew out of that Christian north.

The push south came in bursts, separated by long truces and plenty of alliances that crossed religious lines. Castile took Toledo in 1085. A Christian coalition defeated the Almohads (a North African Muslim dynasty ruling al-Andalus) at Las Navas de Tolosa in 1212. Córdoba fell in 1236 and Seville in 1248. By the late 1200s, the Emirate of Granada in the far south was the last Muslim-ruled kingdom on the peninsula, and it lasted until 1492.

Three faiths under shifting rulers, 1200-1450

In the 1100s, scholars in Toledo were translating Arabic texts into Latin in a city Christian Castile had taken from Muslim rule in 1085. That mix is why the Reconquista is evidence for the course's claim that Christianity, Judaism, and Islam kept shaping European society. Iberia is the clearest Western European case where all three lived side by side in large numbers.

Conquest didn't instantly empty out a city. Muslims living under Christian kings (called Mudéjars) and Jewish communities stayed, paid special taxes, and lived under legal limits. Toledo became a center where Arabic texts, including Arabic versions of Greek philosophy and science, were translated into Latin in the 1100s. So the same frontier produced both religious war and intellectual exchange.

A multiple-choice stimulus about medieval Iberia could ask you to recognize both the religious conflict and the intellectual exchange. In a short-answer question, a strong response names a specific mechanism (translation in Toledo, taxes on religious minorities, the Church backing the wars) instead of just saying "religion mattered."

Castile and Aragon as an exception to fragmentation

Topic 1.6 also asks why political power in Europe was spread out among many lords and decentralized monarchies. Iberia fits that pattern for most of the period: several competing Christian kingdoms, powerful nobles, and frontier towns with their own privileges.

The Reconquista slowly pushed the other way. Shared religious war gave kings a reason to build armies, reward loyal nobles with conquered land, and claim the Catholic Church's support. Ferdinand and Isabella's 1469 marriage laid the groundwork for a dynastic union after Isabella became queen of Castile in 1474 and Ferdinand became king of Aragon in 1479.

Be careful with the word "unified." Castile and Aragon kept separate laws and institutions under the shared rulers. The more accurate description is a dynastic union that strengthened the rulers' ability to pursue shared goals, while still falling short of a single modern state. That nuance could help support a complexity point in a long essay if you develop it as part of an evidence-based argument.

1492: Granada, expulsion, and the Atlantic

Granada surrendered in January 1492. The Spanish Inquisition, set up in 1478, was already investigating converts suspected of secretly practicing Judaism. In 1492 the Alhambra Decree ordered Jews who refused to convert to leave. Within about a decade, Muslims in Castile faced the same choice.

With Granada taken, Isabella and Ferdinand had resources and attention to spare, and they sponsored Columbus that same year. Conquistadors later used methods and justifications that echoed the Reconquista, including rewards of land and labor for conquering on behalf of the crown and the Church.

This makes the Reconquista a useful bridge in a long essay about continuity and change. A strong answer ties a specific Reconquista feature, like religious motivation or crown-granted rewards for conquest, to Spanish expansion in the Americas, and names Granada, 1492, and Ferdinand and Isabella as evidence.

Granada vs. Jerusalem: separating it from the Crusades

Popes granted crusade-style indulgences to Christians fighting in Iberia, which is why the Reconquista and the Crusades are easy to blur together. They do overlap, since both were Christian wars against Muslim powers.

The differences help on a multiple-choice question. The First Crusade was launched in 1095 with the goal of taking Jerusalem, and the crusader states set up in the eastern Mediterranean were eventually lost. Later crusades also targeted places outside the Holy Land, including Iberia. The Reconquista happened inside Europe, began centuries before 1095, and ended with permanent Christian control. If a stimulus centers on Jerusalem, think Crusades. If it mentions Toledo, Córdoba, or Granada, think Reconquista.
