I'll try to further simplify things by putting "territorial markers" before news for each year. But beware: events can not be too neatly labeled that way. Western Europe: The Treaty of Weissenburg carves the HRCEW between Charles’s three “legitimate” sons: Charles II the German, the elder son, receives East Francia (Germany), Bavaria and the imperial title, Theodoric/Pepin obtains the lands from Frisia to Aquitaine and Louis the Pious Burgundy, Provence, Septimania. The three brothers then strike a deal to jointly attack Pepin the Hunchback “to free the Papacy and avenge our beloved father”
