England and France were engaged in the early stages of the Hundred Years' War, with the Battle of Auberoche fought in Northern France in October of this year. In the Iberian Peninsula, Alfonso XI of Castile again besieged the Muslim city of Granada as part of the Reconquista, but without success. The Holy Roman Empire under Louis IV took control of Holland and the surrounding area, granting these lands to his wife Margaret II, Countess of Hainaut in a move which angered many of his princes. Holland was also in the midst of the Friso-Hollandic Wars, engaging with the Frisians on 26 September in the Battle of Warns. Italy, which at the time was divided into several kingdoms, saw several power struggles including the Battle of Gamenario in the north, and the assassination of Andrew, Duke of Calabria in the Kingdom of Naples. In Northern Europe, Swedes continued early stages of their emigration to Estonia, which would continue in the coming decades. Estonian rulers also managed to crush the St. George's Night Uprising in 1345 after a two-year struggle. The Grand Duchy of Lithuania changed hands from Jaunutis to his brother Algirdas in a relatively bloodless shift of power, and Lithuania continued its skirmishes with its northern, Estonian neighbor.
