The Origin of the Kingdom of Castile: Foundations of a Great History
When we speak of the Kingdom of Castile, we speak of an entity that played a crucial and determining role in shaping the history of the Iberian Peninsula and, therefore, of Spain. The roots of the Kingdom of Castile are deeply rooted in the Middle Ages. Its origins go back to a time when the Reconquest, the Christian struggle against the Muslim occupation of Iberia, shaped the geography and destiny of the region.
Historical Context: The Reconquest and the Border Territories
For much of the first millennium AD, the Iberian Peninsula witnessed the coexistence of the cultures of the three great monotheistic religions, Christian, Muslim and Jewish. However, in 711, the Muslim invasion marked the beginning of a period of Islamic domination that would last for almost eight centuries. The Reconquista, a process of land reclamation by the Christian kingdoms, began to take shape in the north of the peninsula.
Castile emerged as a border territorial entity during the 9th and 10th centuries in the so-called “Middle Mark”, a buffer region between the Christian and Muslim territories. The Middle Mark was an area of constant conflict, and the local lords, known as “comes”, played a key role in the defence and expansion of the Christian frontiers.
The Counts of Castile: Pioneers of the Reconquest
In this context, the counts of Castile played a crucial role in the struggle against Muslim rule. The figure of Fernán González, Count of Castile at the beginning of the 10th century, was fundamental in the consolidation of this territorial entity. His leadership in battles such as that of Simancas and his ability to maintain cohesion among the local lords laid the foundations for Castile’s independence and expansion.
Castile’s Autonomy: 11th and 12th Centuries
The 11th century saw the consolidation of Castile as an independent kingdom. In this period, Sancho III the Great, King of Pamplona, divided his kingdom among his sons, assigning Ferdinand I the County of Castile. The death of Alfonso VI in 1109 marked the complete independence of Castile, separating it from the neighbouring Kingdom of León.
During the 12th century, Ferdinand I’s successors, especially Alfonso VII, carried out a series of administrative reforms that strengthened Castilian institutions. The creation of the first courts and the promulgation of the Charter of León are examples of this process. The connection with the Church was also fundamental, with the creation of the diocese of Burgos in 1075.
The Battle of Las Navas de Tolosa and the Christian Advance
The Battle of Las Navas de Tolosa, dated 1212, was a crucial milestone in the Reconquista and had profound implications for Castile. The Christian victory in this battle marked the decline of Almohad power on the Iberian Peninsula and opened the door to southward expansion. Castile, under the reign of Alfonso VIII, contributed significantly to this victory, consolidating its position as a key kingdom in the struggle against Muslim rule.
The Union of Castile and León: 13th Century
The 13th century saw the union of the kingdoms of Castile and León under the Crown of Ferdinand III. The conquest of important cities such as Cordoba and Seville further extended the territories under his control. The mixture of diplomatic, military and religious efforts during this period contributed to the creation of an increasingly powerful kingdom and laid the foundations for the future Spain as we know it today.
