The results of the research project show that the prevalence of large estates (latifundia) in modern and contemporaneous Andalusia was the consequence, in part, of the Frontier of Granada. The defense needs derived from the existence of the frontier with the Nasrid Kingdom of Granada gave rise to the concentration of land ownership and political power in the hands of the nobility. This fact constituted the starting point for the high economic and political inequality that has characterized a great bulk of the Andalusian territory since then.
