Foundation and First Mentions
The history of settlement in the territory of modern Soria is rooted in the Iron Age and is closely intertwined with the fate of the legendary Celtiberia and neighbouring Numantia. However, the foundation of the city in its current form dates back to the Middle Ages. The official establishment of Soria as a fortified urban centre is associated with the beginning of the 12th century (approximately 1109–1119), when the King of Aragon, Alfonso I the Battler (El Batallador), repopulated these lands, securing the borders of the Christian domains.
Key Factors of Establishment
The transformation of a small settlement into an important city was driven by several factors:
- Geographical Location: The city was founded on a strategically advantageous elevation on the right bank of the Duero River, between the Castle and Mirón hills, which provided natural protection and control over river crossings.
- Border Status: For a long time, Soria was situated at the intersection of the interests of three kingdoms — Castile, Navarre, and Aragon. This turned it into a vital military-political hub and the "key" to the region.
Early Cultural and Economic Features
The economic foundation of early Soria was built on livestock farming. The city became one of the most important centres of the Mesta — a powerful association of sheep farmers. The wool trade contributed to prosperity and attracted merchants.
A unique feature of social and cultural life was the formation of the institution of the "Twelve Lineages" (Los Doce Linajes). This association of noble families effectively governed the city, possessed extensive privileges, and used its own seal, creating a special aristocratic atmosphere, traces of which are still visible in the city's architecture today.
