Autumn –Subutai is assigned a new campaign by Genghis Khan against the Tanguts. He crosses the Gobi Desert with a Mongol army and advances south into the Western Xia (or Xi Xia). Meanwhile, Genghis, in his mid-sixties, becomes wounded during hunting. His injury – a dislocated shoulder, perhaps, or a bruised rib – forces him to take some rest.[1]
Iltutmish, Ghurid ruler of the Delhi Sultanate, repels a Mongol attack and invades Bengal. His rival, Ghiyasuddin, leads an army to halt Iltutmish's advance, but decides to avoid a conflict by paying him tribute and accepting his suzerainty.[2]
Europe
July 25– Emperor Frederick II takes an oath at San Germano (near Cassino) and promises to depart on a Crusade (the Sixth Crusade), for the Near East in August 1227. He sends 1000 knights to the Levant and provides Rome with 100,000 ounces of gold, to be forfeited to the Catholic Church should he break his vow. These funds will be returned to Frederick once he arrives at Acre.[3]
February 11– The Charter of the Forest is restored to its traditional rights by King Henry III. 'Free men' are allowed to find pasture for their pigs, collect firewood, graze animals, or cut turf for fuel. At this time, however, only about 10 percent of the population is 'free', the rest are locked into service to a local landowner, some of them little more than slaves.[5]
The Magna Carta is reaffirmed (for the third time) by Henry III, in return for issuing a property tax. It becomes the definitive version of the text.[6]
The 8-year-old Henry I (the Fat) is crowned as king of Cyprus in the Cathedral of Saint Sophia at Nicosia. His uncle Philip of Ibelin orders the coronation, so that when Henry comes of age at fifteen a regency could not be prolonged on the ground that he is not yet crowned.[7]
