John’s position at the beginning of his reign was good. He was accepted in England; he was strong enough to refuse the Scottish King’s demands on Northumberland and Cumberland; the Counts of Flanders and Boulogne made offers of friendship; and Otho of Germany even pressed him not to make peace with the French king, promising to come to his assistance. It was from Philip only that he appeared to have to dread any danger; for that king’s early friendship for him had now changed to hatred, as he declared because he had accepted his continental dominions without asking leave of him, his feudal superior. We have thus early the key to the policy of Philip Augustus, who was determined to make use of the letter of the feudal law to bring his great vassal into subjection and establish royalty in France. He had a ready weapon in the person of young Arthur, who had already done homage to him for Maine, Anjou, Touraine, and Brittany. The efforts of the Church were however constantly exerted to keep the peace between these rivals; and Philip had a difficulty on his own hands which induced him to desire peace. He had married Ingelborga of Denmark, but had almost immediately separated from her and married Agnes de Méranie. The cause of the divorced princess was warmly taken up at Rome, and in this year Innocent III. had laid France under an interdict. [Sidenote: Peace with Philip, and marriage treaty.] [Sidenote: Marriage with Isabella de la Marche.] [Sidenote: Homage of Scotland.] Under these circumstances a treaty was patched up. John promised to young Louis, the heir of France, the hand of his niece Blanche of Castile, and along with her the Earldom of Evreux; at the same time pledging himself not to assist his nephew Otho against the rival Emperor of Germany, Philip of Swabia. Philip in return secured to England the disputed province of the Vexin, and for the time dropped the claims of Arthur. A formal interchange of homage was then made; on the part of John for his French possessions, on the part of Louis for his newly acquired earldom, on the part of Arthur for his provinces in France. John at once began to destroy his good position. A large aid gathered before his coronation, and another for the purpose of paying a sum of money demanded by the late treaty, had already excited anger in England. He now proceeded to rouse the displeasure of some of his chief French nobles. He put away his wife Hadwisa, the daughter of the Earl of Gloucester, and was beginning to treat for the hand of a Portuguese princess, when he suddenly fell in love with Isabella, the daughter of the Count of Angoulême, and carried her off from her betrothed husband, the Count de la Marche. Before the storm broke, however, he was able to oblige the Scotch king, with whom he had been in constant correspondence, to meet him at Lincoln, and there to do him homage, and to swear to be his liegeman for life, limb and land.
