Events By place Europe August 8 – Emperor Henry VII begins a campaign against Robert of Naples (the Wise), king of Naples. Henry's allies are loath to join him and his army (some 15,000 man) is supported by 4,000 knights, while the imperial fleet is prepared to attack Robert's realm directly. Henry besieges the city of Siena, but within a week, he succumbs to malaria and dies at Buonconvento on August 24. After the death of Henry, his 17-year-old son John of Bohemia succeeds him, who becomes one of the seven prince-electors of the Holy Roman Empire. November 9 – Battle of Gammelsdorf: German forces led by Louis IV (the Bavarian) defeat his cousin Frederick I (the Fair) at Gammelsdorf, who is supported by Leopold I (the Glorious). During the battle, Louis' smaller force does not pursue Frederick's defeated army. He is forced to renounce his tutelage over the young dukes of Lower Bavaria (Henry XIV, Otto IV and Henry XV). The conflict causes a stir within the Holy Roman Empire. November 18 – Queen Constance of Portugal, mother of the 2-year-old King Alfonso XI (the Avenger), dies. Alfonso's grandmother Queen dowager María de Molina, his uncle Peter of Castile, and his great-uncle John of Castile divide the regency over the young Alfonso. While Maria takes charge of his education, the infantes, especially Peter, assume the duty of defending Castile. England June – Scottish forces led by Edward Bruce besiege Stirling Castle, which is held by an English garrison under Philip Mowbray. Shortly after, Mowbray proposes a bargain: if the English army has not reached the castle by midsummer in 1314, he will surrender the castle to the Scots. Bruce agrees to this and lets Mowbray leave the castle to inform King Edward II of the agreement. October – King Robert I (the Bruce) calls upon a meeting of the Scottish nobles at an assembly in Dundee. There, he gives the Scots who have not yet come into his peace agreement a year to swear fealty to him or lose all their estates.
