One “alien king” of this name was able to come to a tentative agreement with the nobles of the region he ostensibly ruled with the so-called “inaugural diplomas.” An exiled knight offered an axe-wielding king with this name the option to surrender after the king’s helmet fell off. Another ruler of this name failed to relieve a siege at the Château Gaillard (“shah-TOH guy-YAHR”)after a bungled synchronized land–sea campaign. A ruler of this name from the House of Luxembourg suffered from ophthalmia until his 1346 death. The Jacquerie occurred under a king of this name, whose capture resulted in a large ransom payment in the Treaty of Brétigny (“bray-teen-YEE”). A blind Bohemian king who died at Crécy had this name, as did a king who lost the First Barons’ War and signed an agreement at Runnymede in 1215 that limited royal taxes. For 10 points, give the name of the English king who signed the Magna Carta. ■END■
