King Henry I, son of William the Conquerer, furthered peace between the Normans and native English by his marriage to a niece of King Edward the Confessor called Matilda. She married him on condition that he grant a charter of rights undoing some practices of the past reigns of William I and William II. Peace was also furthered by the fact that Henry I had been born in England and English was his native tongue. The private wars of lords were now replaced by less serious mock battles. 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. Although illiterate, 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 of the kingdom in Henry's absence, as William's queen had for him. Both queens received special coronation apart from their husbands; they held considerable estates which they administered through their own officers, and were frequently composed of escheated honors. Matilda was learned and a literary patron. She founded an important literary and scholastic center. Her compassion was great and her charities extensive. In London she founded several almshouses and a care- giving infirmary for lepers. These were next to small monastic communities. She also 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.
