Most Spanish gifts of land specifically mentioned the Templar's military function as a frontier guard for the Spanish crusade. This indicates that they had already scored some military successes on the peninsula that the chroniclers did not report; the Spanish had neither the funds nor the patience to support a group that could not substantially help in the Reconquista of the Iberian peninsula.
Though the Templars were not yet a military power of note in Palestine, they were already one in Spain. So established were they in local politics by 1134 that when King Alfonso I (the Battler) of Aragon died childless that year, he left a third of his kingdom to the Templars. He left another third each to the Hospitallers and to the obscure Canons of the Holy Sepulchre." All three Orders originated in the Holy Land only one and a half decades earlier (TN).

Instead, they believe that he had written his will (with the knowledge of his beneficiaries) to continue his line by giving his brother time to escape his vows and establish his own power base.
The scandal of Alfonso's will created temporary resentment against these orders amongst the other clerics, but also raised their profile in the peninsula. For an Order like the Temple, which had been founded only fifteen years before, and officially recognized only five years previously, it was a propaganda coup. (...)"
