"An astonishing enthusiasm was excited throughout Christendom in behalf of the Templars. Princes and nobles, sovereigns and their subjects, vied with each other in heaping gifts and benefits upon them, and scarce a will of importance was made without an article in it in their favour. Many illustrious persons on their deathbeds took the vows, that they might be buried in the habit of the order. And sovereigns, quitting the government of their kingdoms, enrolled themselves amongst the holy fraternity, and bequeathed even their dominions to the Master and the brethren of the Temple.
Thus, Raymond Berenger, Count of Barcelona and Provence, at a very advanced age, abdicating his throne, and shaking off the ensigns of royal authority, retired to the house of the Templars at Barcelona, and pronounced his vows (A.D. 1130) before brother Hugh de Rigauld, the Prior. His infirmities not allowing him to proceed in person to the chief house of the order at Jerusalem, he sent vast sums of money thither, and immuring himself in a small cell in the Temple at Barcelona. He there remained in the constant exercise of the religious duties of his profession until the day of his death.
At the same period, the Emperor Lothaire bestowed on the order a large portion of his patrimony of Supplinburg. And the year following (A.D. 1131,) Alphonso the First, king of Navarre and Arragon, also styled Emperor of Spain, one of the greatest warriors of the age, by his will declared the Knights of the Temple his heirs and successors in the crowns of Navarre and Arragon. A few hours before his death he caused this will to be ratified and signed by most of the barons of both kingdoms. The validity of this document, however, was disputed, and the claims of the Templars were successfully resisted by the nobles of Navarre. But in Arragon they (The Knights templar, TN) obtained, by way of compromise, lands, and castles, and considerable dependencies, a portion of the customs and duties levied throughout the kingdom, and of the contributions raised from the Moors."
