[Sidenote: Second war; against Richard. 1184.] [Sidenote: Third war. 1187.] Constantly unwise in his conduct to his sons, Henry now demanded from Richard, perhaps as a recompense for his assistance, a part of Aquitaine, to be given to his favourite son John. This Richard refused to give, and consequently both John and Geoffrey of Brittany attacked him. But though Geoffrey was thus ready enough to quarrel with his elder brother, it was from no love of his father that he did so. He, as well as Richard, was hurt by Henry’s evident partiality for John. He took the opportunity of putting in his own claim for Anjou. On Henry’s refusal, he at once fled to France, where he was as usual well received. His death relieved his father for the time from his opposition, but sowed the seed of further difficulties; for on the one hand his province Brittany was at once divided between the French and English faction, and on the other King Philip II. raised claims as overlord to the guardianship of his young son Arthur. There was a growing disinclination however on all sides to plunge into war; for the Pope was constantly urging a general peace, and the combination of Christian princes for the great Eastern Crusade. A succession of weak princes, and the unnatural and artificial character of the feudal kingdom of Jerusalem, together with the rise of the new Mahomedan power of the Saracens under Saladin, had reduced European power in the East to a very low ebb; and in 1184, Heraclius, the Bishop of Jerusalem, had found it necessary to come over, to attempt to persuade the Kings of England and France to embark in a new crusade. But to Henry, although under a pledge to join such an expedition, the idea of leaving his European dominions in their present critical situation was very distasteful, and he consequently postponed taking action. The feeling however that a crusade was imminent rendered hostilities more difficult; so that when, in 1187, the arbitrary behaviour of Richard in Aquitaine had produced fresh difficulties with France, which as usual terminated in the flight of Richard and the junction of his interests with those of his father, the news of the great battle of Hettin, in which the flower of the Christian army of Jerusalem had been entirely destroyed, and the arrival of William of Tyre for the purpose of exciting the enthusiasm of the West, put a sudden end to the hostilities; and, in 1188, the two kings met in perfect friendship under the old elm in the neighbourhood of Gisors, which was their usual place of treaty, and joined with apparent heartiness in taking the Cross. Upon this occasion Henry imposed upon England the tax, known as the Saladin tax, which was a tenth on all property, and in the collection of which the King’s officers were to work hand in hand with the Church.
