The history of Bilbao is the story of the transformation of a small fishing village into an important economic and cultural centre. The city, which grew on the banks of the Nervión River, owes its development to a successful combination of geographical location, the enterprising spirit of its inhabitants, and key historical decisions.
Foundation and First Records
The official date of the foundation of Bilbao is considered to be 15 June 1300. On this day, the Lord of Biscay, Don Diego López V de Haro, issued the town charter, granting the settlement the status of a town and special privileges. This decree was confirmed by King Ferdinand IV of Castile in 1301, which consolidated the legal status of the new city. Although archaeological findings indicate earlier settlements on this site, it was the charter of 1300 that gave the impetus for Bilbao's rapid development.
Key Factors of Development
The city owes its growth and prosperity to several fundamental factors:
- Strategic Location: Its location at the estuary of the navigable Nervión River, a few kilometres from the Bay of Biscay, made Bilbao a natural port linking Castile with Northern Europe.
- Trade and Resources: Initially, the city's economy was built on the export of iron extracted from nearby mines and Castilian wool. The port quickly became the region's main trading window.
- Political Privileges: The charter (fueros) granted to the city gave residents significant trade and tax exemptions, attracting merchants and artisans to Bilbao.
Early Cultural and Economic Features
The core of early Bilbao became the area known today as the Old Town (Casco Viejo), which originally consisted of seven streets (Las Siete Calles). Economic life was entirely focused around the port and trade. The most important infrastructure object was the San Antón Bridge, which for centuries remained the only crossing over the river, serving as a key link on the trade route from Castile. The city was also located on one of the routes of the pilgrimage Way of St. James, which contributed to its cultural development and the construction of churches.
