Foundation and First Mentions
The origins of Alcalá de Henares date back to antiquity, but it emerged as a significant urban center during the Roman era in the 1st century AD under the name Complutum. It was the only Roman city in the modern-day Madrid region to possess a complete urban structure.
The city owes its current name to the period of Muslim rule. In the Middle Ages, the center of the settlement shifted to higher ground for defense, where a fortress was built — Al-Qal'at (translated from Arabic as "castle" or "fortress"). Later, after the return of the Christians, the suffix "de Henares" was added, named after the nearby river.
Key Factors in Its Development
The transformation of a small settlement into an important historical center was due to several factors:
- Geographical Location: The city emerged in the fertile valley of the Henares River, which ensured food security and access to water.
- Transport Accessibility: One of the peninsula's most important roads passed through Roman Complutum, connecting Zaragoza (Caesaraugusta) and Mérida (Emerita Augusta), which facilitated active trade.
- Religious Status: In the 4th century, the Christian martyrs—the children Justo and Pastor—were executed here. Their burial site became an important center of pilgrimage during the Visigothic period, maintaining the city's significance even during eras of decline.
Early Cultural and Economic Features
Already in the Roman period, the region's economy was highly developed. Archaeological finds, such as the House of Hippolytus, testify to the wealth of local landowners and the presence of a sophisticated urban culture with mosaic schools and public baths.
After the Reconquista in 1118, the city began to develop as a center for the peaceful coexistence of three cultures: Christian, Jewish, and Muslim. The Jewish community played a vital role in trade and crafts, while royal privileges for holding fairs laid the foundation for the economic prosperity that preceded the opening of the famous university.
