Year 1225 (MCCXXV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. Events By place Mongol Empire 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. 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. 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 forfeit to the Catholic Church should he break his vow. These funds will be returned to Frederick once he arrives at Acre. November 9 – Frederick II marries the 14-year-old Queen Yolande, heiress to the kingdom of Jerusalem, and adds the Crusader States to his dominions. November 29 – The 12-year-old Henry VII, by order of his father Frederick II, marries Margaret of Austria, daughter of Duke Leopold VI (the Glorious). The Teutonic Knights are expelled from Transylvania by King Andrew II, because they wanted to separate from Hungary. England 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. 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. Middle East Summer – Battle of Garni: Khwarezmid forces led by Jalal al-Din Mangburni defeat the Georgian army (some 70,000 men) at Garni. The royal court of Queen Rusudan moves to Kutaisi, while the Georgian capital Tbilisi is besieged by the Khwarezmians. July 25
