From the Guadalteba and Yeguas rivers, the border took a north-west direction, with some variations, running through the mountains south of Benameji, Rute, Priego de Cordoba and Alcala la Real.
[3] All the territory of Alicante and Orihuela, including the southern portion of the Kingdom of Valencia, from Alcoy and Cocentaina to the sea, formed a border area as well.
The characteristics of this area caused kings to grant many rights and privileges to border towns in order to improve the attractiveness of life in those places, for even in times of peace there was a permanent risk of being caught or dying due to Grenadines frequent raids.
The society of the frontier populations was characterized by isolation from other regions, derived from a position adjacent to the enemy and therefore by fundamental characteristics based on military activity, which explained the concerns of councils counting on those with the economic capacity to maintain horses and weapons, in addition the infantry formed the majority of the army, and also opportunists who arrived to smuggle goods across the other side of the border, and even those convicted of violent crimes who sought to redeem themselves and avoid punishment by serving the mighty.
The settlements were established through a number of fortified cores, close together, with limited extension and a scarce density of population, and with only military functions that were above all else defensive.
Therefore, the basic economic wealth of the frontier populations was through the activity of ranching, as livestock, especially sheep and goats that could be transported and secured behind the walls of fortresses and cities in case of a Moorish attack.
