4 8o THE HISTORY OF MEDIEVAL EUROPE Although the Great Charter is the most important single document in English medieval history, it was not the m:st Granting of instance of a written charter in which a king of kings e before England made promises and concessions to his John people. William Rufus seems to have made merely verbal promises of good government in order to secure English support against his older brother Robert, whose claim to the throne the Norman barons were inclined to support. At any rate, whatever promises Rufus made, he did not keep them. But Henry I had issued at the open- ing of his reign a written charter of liberties in fourteen articles promising to abolish the evils of Rufus's reign.
