King Henry III of England issued the Charter of the Forest, re-establishing the rights of access of free men to royal forests.

Henry III, also known as Henry of Winchester, was King of England, Lord of Ireland and Duke of Aquitaine from 1216 until his death in 1272. The son of John, King of England, and Isabella of Angoulême, Henry acceded to the throne when he was only nine in the middle of the First Barons' War. Cardinal Guala Bicchieri declared the war against the rebel barons to be a religious crusade and Henry's forces, led by William Marshal, defeated the rebels at the battles of Lincoln and Sandwich in 1217. Henry promised to abide by the Great Charter of 1225, a later version of Magna Carta (1215), which limited royal power and protected the rights of the major barons. Henry's early reign was dominated first by William Marshal, and after his death in 1219 by the magnate Hubert de Burgh, Earl of Kent. In 1230 the King attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle. A revolt led by William Marshal's son Richard broke out in 1232, ending in a peace settlement negotiated by the Catholic Church.

The Charter of the Forest of 1217 re-established rights of access for free men to the royal forest that had been eroded by King William the Conqueror and his heirs. Many of its provisions were in force for centuries afterwards. It was originally sealed in England by the young King Henry III, acting under the regency of William Marshal, 1st Earl of Pembroke.

Free tenants, also known as free peasants, were tenant farmer peasants in medieval England who occupied a unique place in the medieval hierarchy. They were characterized by the low rents which they paid to their manorial lord. They were subject to fewer laws and ties than villeins. The term may also refer to the free peasants of the Kingdom of France, part of an ordering of classes with legal privileges who constituted the third estate, a land-owning non-political peasantry, mostly different from other countries with estates.
