At his accession, there was a firm foundation of a national law administered by a centralized judicial system, a centralized executive, and an organized system of local government in close touch with both the judicial and the executive system. To gain knowledge of his nation, he sent royal commissioners into every county to ask about any encroachments on the King's rights and about misdeeds by any of the King's officials: sheriffs, bailiffs, or coroners. The results were compiled as the "Hundred Rolls". They were the basis of reforms which improved justice at the local as well as the national level. They also rationalized the array of jurisdictions that had grown up with feudal government. Statutes were passed by a parliament of two houses, that of peers (lords) and that of an elected [rather than appointed] commons, and the final form of the constitution was fixed. Wardships of children and widows were sought because they were very profitable. A guardian could get one tenth of the income of the property during the wardship and a substantial marriage amount when the ward married. Parents often made contracts to marry for their young children. This avoided a forced marriage by a ward should the parents die. Most earldoms and many baronages came into the royal house by escheat or marriage. The royal house employed many people. The barons developed a class consciousness of aristocracy and became leaders of society. Many men, no matter of whom they held land, sought knighthood. The king granted knighthood by placing his sword on the head of able-bodied and moral candidates who swore an oath of loyalty to the king and to defend "all ladies, gentlewomen, widows and orphans" and to "shun no adventure of your person in any war wherein you should happen to be". A code of knightly chivalry became recognized, such as telling the truth and setting wrongs right. About half of the knights were literate. In 1278, the king issued a writ ordering all freeholders who held land of the value of at least 400s. to receive knighthood at the King's hands. At the royal house and other great houses gentlemanly jousting competitions, with well-refined and specific rules, took the place of violent tournaments with general rules. Edward forbade tournaments at which there was danger of a "melee". At these knights competed for the affection of ladies by jousting with each other while the ladies watched. Courtly romances were common. If a man convinced a lady to marry him, the marriage ceremony took place in church, with feasting and dancing afterwards. Romantic stories were at the height of their popularity. A usual theme was the lonely quest of a knight engaged in adventures which would impress his lady.
