George, Duke of Saxony
The Saxon feud (Dutch: "Saksische Vete"; Frisian: "Saksyske Skeel"; German: "Säschische Fehde") was a military conflict in the years 1514–1517 between the East Frisian Count Edzard I, 'West Frisian' rebels, the city of Groningen, and Charles II, Duke of Guelders on the one hand and the Imperial Frisian hereditary governor George, Duke of Saxony – replaced by Charles V of Habsburg in 1515 – and 24 German princes. The war took place predominantly on East Frisian soil and destroyed large parts of the region.
