History of the Disappearance of Islam from the Iberian Peninsula

The history of the Iberian Peninsula is a vivid tapestry woven with the threads of various ruling empires, among which the Muslim rule stands out for its duration and impact.

From the early 8th century, the lands now known as Spain and Portugal were under Muslim control, a period characterized by religious, cultural, and scientific prosperity.

However, by the 17th century, the visible practice of Islam had almost completely vanished from the peninsula. This drastic change was the result of centuries of political shifts, religious conflicts, and social transformations.

In the article below, World History Edu takes an in-depth look at the disappearance of Muslim majority from the Iberian Peninsula.

Early Muslim Conquest and the Establishment of Al-Andalus

The Muslim rule in the Iberian Peninsula began with the invasion led by the Berber general Tariq ibn-Ziyad in 711 AD. This event marked the start of an era that would see the peninsula under Islamic rule for the next 800 years, known as Al-Andalus.

The Muslims quickly established a sophisticated civilization known for its architectural marvels, such as the Great Mosque of Córdoba, and its significant contributions to various fields of knowledge.

The Christian Reconquista

Parallel to the flourishing of Islamic culture and society in Al-Andalus, the northern Christian kingdoms were slowly gaining strength. This period saw the beginning of the Reconquista, a series of campaigns by Christian states to reclaim territory from the Muslim rulers.

The Reconquista is characterized by a slow but steady north-to-south push by the Christian forces, which culminated in the capture of Toledo in 1085, a significant blow to Muslim power in the peninsula.

Over the centuries, the balance of power continued to shift until 1492, when the Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile conquered Granada, the last Muslim stronghold. This event marked the end of Muslim political rule in the Iberian Peninsula but not the end of the Muslim presence.

The Status of Muslims Post-Reconquista

After the fall of Granada, Muslims in the newly Christian territories, now called Moriscos, were initially allowed to continue practicing their religion. However, this tolerance was short-lived.

The late 15th and early 16th centuries saw a growing sentiment of religious uniformity driven by the Reconquista’s ideological and religious underpinnings. In 1492, the same year Granada fell, the Alhambra Decree forced the expulsion or conversion of Jews, setting a precedent for the treatment of Muslims.

By the mid-16th century, all Muslims in Spain were decreed to convert to Christianity or face expulsion under the policies of forced conversion. These converted Muslims, or Moriscos, were suspected of secretly practicing Islam, which led to tensions with the Christian majority.

Cultural Resistance and Forced Conversions

Despite outwardly adopting Christianity, many Moriscos maintained their Islamic practices in secret. This clandestine adherence to Islam included subtle resistances such as dietary preferences, marriage customs, and clandestine religious gatherings. The Spanish Inquisition, established to enforce Catholic orthodoxy, often targeted Moriscos, intensifying the scrutiny and persecution they faced.

The situation escalated to a point where the mere retention of Muslim customs, such as the Arabic language and Islamic dress, was seen as a threat to the Christian social order. This resulted in increasing legislative pressures and social ostracism against the Moriscos.

Expulsion of the Moriscos

The final blow came in the early 17th century when King Philip III signed a decree in 1609 ordering the expulsion of the Moriscos. This decision was influenced by the fear of an internal threat more than any proven disloyalty.

The expulsion process, which lasted until 1614, was brutal and thorough, effectively removing the majority of the Morisco population from the Iberian Peninsula.

It is worth mentioning the fact that the expulsion had severe demographic and economic impacts, as the Moriscos had been integral to the agricultural and artisanal economy of the peninsula. Their removal led to a significant loss of population and expertise, which affected the local economies for decades.

The disappearance of the Muslim majority from the Iberian Peninsula is a poignant chapter in European history, illustrating the profound impacts of religious and political upheaval.

The legacy of this period is still evident in the architectural, cultural, and linguistic traces that pepper the landscape of modern Spain and Portugal.
