Henry was a shrewd judge of character and of the course of events, cautious before taking action, but decisive in carrying out his plans. He was faithful and generous to his friends. He showed a strong practical element of calculation and foresight. He was intelligent and a good administrator. He had an efficient intelligence gathering network and an uncanny knack of detecting hidden plans before they became conspiratorial action. He made many able men of inferior social position nobles, thus creating a class of career judges and administrators in opposition to the extant hereditary aristocracy. He loved books and built a palace at Oxford to which he invited scholars for lively discussion. Queen Matilda served as regent in Henry's absence. She was literate and a literary patron. Her compassion was great and her charities extensive. She founded a care-giving hospital and had new roads and bridges built. Henry issued charters restoring customs which had been subordinated to royal impositions by previous Kings, which set a precedent for later Kings. His coronation charter describes certain property rights he restored after the oppressive reign of his brother. "Henry, King of the English, to Samson the bishop, and Urse of Abbetot, and to all his barons and faithful vassals, both French and English, in Worcestershire, greeting. [1.] Know that by the mercy of God and by the common counsel of the barons of the whole kingdom of England I have been crowned king of this realm. And because the kingdom has been oppressed by unjust exactions, I now, being moved by reverence towards God and by the love I bear you all, make free the Church of God; so that I will neither sell nor lease its property; nor on the death of an archbishop or a bishop or an abbot will I take anything from the demesne of the Church or from its vassals during the period which elapses before a successor is installed. I abolish all the evil customs by which the kingdom of England has been unjustly oppressed. Some of those evil customs are here set forth. [2.] If any of my barons or of my earls or of any other of my tenants shall die his heir shall not redeem his land as he was wont to do in the time of my brother [William II (Rufus)], but he shall henceforth redeem it by means of a just and lawful 'relief`. Similarly the men of my barons shall redeem their lands from their lords by means of a just and lawful 'relief`.
