question: Erard and Philippa landed in France in January 1216. On their journey to Le Puy-en-Velay, Erard was arrested by agents of the king of France but managed to escape and get to Champagne. Erard and his supporters took up a position in Noyers, which Blanche of Navarre then besieged in April 1216. That same month Erard accepted a truce and submitted the matter to the king of France for arbitration. In July 1216, King Philip II finally heard Erard's suit at Melun, but ruled in Blanche's favor due to the overwhelming evidence she provided: the barons of the realm had sworn to support Theobald III should Henry II not return from the Holy Land, Theobald III had done homage to the king in 1198, Blanche had done homage to the king in 1201, and Theobald IV himself had made an innovative "anticipatory homage" in 1214. Blanche even provided numerous letters patent, bearing the seals of the barons who had sworn homage. Philip II ordained that the barons await the majority of Theobald IV and his assumption of his rights as Count . Philip II ordered Erard and the barons to seal their own letters patent confirming the court's decision and promising to observe a truce.

question: In Britain, free trade became a central principle practiced by the repeal of the Corn Laws in 1846. Large-scale agitation was sponsored by the Anti-Corn Law League. Under the Treaty of Nanking, China opened five treaty ports to world trade in 1843. The first free trade agreement, the Cobden-Chevalier Treaty, was put in place in 1860 between Britain and France, which led to successive agreements between other countries in Europe. Many classical liberals, especially in 19th and early 20th century Britain and in the United States for much of the 20th century , believed that free trade promoted peace. Woodrow Wilson included free-trade rhetoric in his "Fourteen Points" speech of 1918:
