The main city is located 121 meters above sea level, with the Sierra Morena to the north and countryside to the south.

The transition to the historical period is testified by the material remains ascribable to the Final Orientalizing Bronze, located in sites at the confluence of the Guadalquivir and the Guadiato River [es], and also in Cerro del Castillo.

The chronicles mention the population in that year, when the caliph of Damascus appointed the lord of Almodóvar, Add al-Malik ben Qatan, to occupy the emirate of al-Andalus for the second time until he died in the civil war against the Syrians.

Likewise, its notable location and the impregnability of its walls led to it being used as the residence of the monarchs Peter I and Henry II, and as a prison, as attested to by an order of the Royal Council (1491).

Around 1473 the name Almodóvar del Río appears for the first time, a toponym intended to refer to its location on the banks of the Guadalquivir.

Its population decreased during this period: from 1,600 residents in 1530 to 800 at the end of the Modern Age; The majority were dedicated to field work as day laborers.

The liberal revolution, which occurred in Spain and Portugal at the beginning of the 19th century, had far-reaching socioeconomic repercussions in the town, since the disappearance of the manorial regime and the ecclesiastical and municipal confiscations had an impact on the consolidation of the latifundia within the area, which generated a high social conflict, which manifested itself during the Second Republic and the Spanish Civil War.
