As the only surviving adult son of Charlemagne and Hildegard, he became the sole ruler of the Franks after his father's death in 814, a position which he held until his death, save for the period 833–34, during which he was deposed. In fulfillment of an oath, Louis founded Ettal Abbey on 28 April 1330 on his return from Italy. This victory caused a stir within the Holy Roman Empire and increased the reputation of the Bavarian Duke. He is buried in the Frauenkirche in Munich. [12], Emperor Louis also allied with King Edward III of England in 1337 against King Philip VI of France, the protector of the new Pope Benedict XII in Avignon. When Louis’s own imperial vicar forced the pope and Robert to raise the siege of Milan, the heresy proceedings were extended to Louis himself, who was excommunicated in March 1324. Louis was born in Munich, the son of Louis II, Duke of Upper Bavaria and Count Palatine of the Rhine, and Matilda, a daughter of King Rudolph I. Louis IV was Duke of Upper Bavaria from 1294/1301 together with his elder brother Rudolf I, served as Margrave of Brandenburg until 1323, as Count Palatine of the Rhine until 1329, and he became Duke of Lower Bavaria in 1340. In 1337 he allegedly bestowed upon the Teutonic Order a privilege to conquer Lithuania and Russia, although the Order had only petitioned for three small territories. Louis IV (German: Ludwig; 1 April 1282 – 11 October 1347), called the Bavarian, of the house of Wittelsbach, was King of the Romans from 1314, King of Italy from 1327, and Holy Roman Emperor from 1328. He failed, however, to achieve a lasting understanding with his Lower Bavarian cousins; that conflict was not settled until this line became extinct in 1340. On the strength of his victory, Louis, in 1314, became the candidate of the Luxembourgs, who had failed to gain the crown for John of Bohemia, the late emperor’s son. Louis, who was impressed by such nobility, renewed the old friendship with Frederick, and they agreed to rule the Empire jointly. The argumentation ill-advisedly dealt with constitutional problems touching on the empire as well as with doctrinal points. Louis IV, byname Louis the Bavarian, German Ludwig der Bayer, (born 1283?, Munich [Germany]—died October 11, 1347, Munich), duke of Upper Bavaria (from 1294) and of united Bavaria (1340–47), German king (from 1314), and Holy Roman emperor (1328–47), first of the Wittelsbach line of German emperors. This codification enabled the empire to stand up to the juridically minded church of Avignon. Through their city magistrates and other representatives, they pressed for legitimization of Louis’s rule and the rejection of papal interference. [1], In 1333, Emperor Louis sought to counter French influence in the southwest of the empire so he offered Humbert II of Viennois the Kingdom of Arles which was an opportunity to gain full authority over Savoy, Provence, and its surrounding territories. The Holy Roman Emperor, originally and officially the Emperor of the Romans (Latin: Imperator Romanorum) during the middle ages, and also known as the German-Roman Emperor since the early modern period (German: Römisch-deutscher Kaiser, lit. A civil war against his brother Rudolf due to new disputes on the partition of their lands was ended in 1313, when peace was made at Munich. Despite Louis' victory, Pope John XXII still refused to ratify his election, and in 1324 he excommunicated Louis, but the sanction had less effect than in earlier disputes between emperors and the papacy. With the Treaty of Pavia in 1329 the emperor reconciled the sons of his late brother Rudolph and returned the Palatinate to his nephews Rudolf and Rupert. Having assured himself of his brother’s goodwill by means of a compromise (June 21, 1313), Louis gained a decisive victory over the Habsburgs at Gammelsdorf (November 9), while the succession to the German crown, fallen vacant with the emperor Henry VII’s unexpected death on August 24, was still the subject of negotiations. The Habsburgs, however, would not acknowledge Louis, though he was grandson of King Rudolf; in the double election of October 19–20, 1314, Louis gained little advantage from the fact that his claims were rather more substantial than those of the anti-king, Frederick III of Austria, crowned on the same day, November 25. Three months later, Louis published a decree declaring Pope John XXII (Jacques Duèze) deposed on grounds of heresy. Yet Louis’s German enemies had not been idle. Keeping her son out of Munich, she sent him to her brother’s court in Vienna, where he was reared, together with his Habsburg cousins, Frederick and Leopold.
