The Charter of Liberties, also called the Coronation Charter, was a written proclamation by Henry I of England, issued upon his accession to the throne in 1100. It sought to bind the King to certain laws regarding the treatment of nobles, church officials, and individuals. The nineteenth-century historians Frederick Maitland and Frederick Pollock considered it a landmark document in English legal history and a forerunner of Magna Carta.
The document addressed abuses of royal power by his predecessor William II (his brother William Rufus), as perceived by the nobility, specifically the over-taxation of the barons, the abuse of vacant sees, and the practices of simony and pluralism.
The Charter of Liberties was generally ignored by monarchs, until in 1213 Archbishop Langton reminded the nobles that their liberties had been guaranteed over a century prior in Henry I's Charter of Liberties.
Henry I of England, nicknamed Beauclerk, was the fourth and youngest son of William I (William the Conqueror) by his queen Matilda of Flanders. The name Beauclerk was given because Henry was well educated, being able to read and write Latin, and possessed a knowledge of English law and natural history. He had received 5,000 pounds of silver from his father, but no land holdings. He used this to purchase a district in the Cotentin Peninsula in Normandy for 3,000 pounds from his brother Robert of Normandy. Robert had been left the Duchy of Normandy by their father, but needed money. Various political intrigues occurred in France, which led to the imprisonment of Henry for two years by his brother William II, then King of England. In 1096, Robert left Normandy for the First Crusade. Henry swore fealty to William, who took over Normandy in Robert's absence. William was killed in a hunting accident on 2 August 1100. (Henry was present on this hunting trip.) With William dead and Robert absent, Henry claimed the English crown.
