Kingdom of Aragon
The king of Saragossa, Al-Musta'in II decided to carry out a plundering expedition against the neighboring Christians in the year 1110 and ended up fighting with the border knights in the battle of Valtierra where he was defeated and killed. The capture of Saragossa in 1118 meant the fall of the entire Moorish kingdom, thus radically changing the social structures and spiritual horizons of the small kingdom of highlanders that until then had been Aragon.
