Western Europe: When Lucie, titular queen of Aquitania/Occitania and last of the Poitou house, dies in exile at the Fois (*OTL Foix) court, her recently widowed brother-in-law Sancho VI of Navarra formally claims the Aquitanian crown by rights of marriage. A Navarrese army reconquers Navarra north of the Pyrenees; duke Lop Guilhem IV of Gascony pays feudal homage to the Navarrese ruler. As Lucie's widowed husband Peyre Berenger, brother of count Bernat V of Fois (*OTL Foix), now claims the crown too, Navarrese forces retake Saragossa, starting the long War of Aquitanian Succession, or Twenty Years' War, that in several bouts of fighting will take place on both sides of the Pyrenees.
