King Alfonso I of Aragon, having no direct heir, bequeathed his dominions to be divided among the Knights Templar, the Knights Hospitaller, and the Order of the Holy Sepulchre, but this bequest was annulled by his subjects in 1131.

Although the Aragonese branch of the order was pronounced innocent at the famous trial of the Templars, Pope Clement V's Bull of suppression was applied to them in spite of the protests of King James II of Aragon in 1312.

[1] King James II persuaded Pope John XXII to permit him to regroup the Templar properties in Aragon and Valencia, and to create a new military order not essentially differing from that of the Templars, which should be charged with the defence of the frontier against the Moors and the pirates.

Pope John XXII approved it on 10 June 1317, and gave it the Cistercian rule.

The office of grand master was united with the Crown by Philip II in 1587.
