The north-eastern and eastern borders of the al Andalus district of Lleida (10th -11th centuries)

La frontera nororiental y oriental del distrito andalusí de Lleida se configura a partir del siglo IX y se rompe a principios del siglo XI, prácticamente coincidiendo con la fitna de 1010. Este vasto territorio se organiza a partir de los cursos fluviales y las llanuras fértiles bien antropizadas como la correspondiente al ager de Guissona (Iesso). Estas realidades geográficas e históricas en forma de herencia territorial clásica, se vertebran desde una perspectiva andalusí, de aquí la instalación de comunidades rurales cerca de los cursos fluviales, la construcción de fortalezas como Calaf, la presencia de ribats en sus proximidades y, se garantiza la comunicación terrestre resiguiendo los valles fluviales o vías de comunicación, también, preexistentes.The north eastern and eastern borders of the Andalusian district of Lleida were shaped from the 9th century onwards and fractured during the early 11th century, almost at the same time as the fitna or unrest of 1010. This vast territory was organised around the river courses and the fertile flood plains which had long been anthropised, such as the ager or public land around Guissona (formerly Iesso). These geographical and historical realities formed a classical territorial legacy structured from an Andalusian perspective, thus the rural communities grew up alongside the river courses, with the construction of fortresses such as Calaf, the presence of ribats or forts in the surrounding area, and land communications were ensured, tracing the course of the river valleys or the pre-existing roads and thoroughfares
