The Guelders Wars broke out in 1502 over an old, unsettled dispute. At the end of the Second War of the Guelderian Succession (1423–1448), Gerhard VII, Duke of Jülich-Berg sold his claims to the Duchy of Guelders to Philip the Good, Duke of Burgundy. In subsequent years, a long-lastig succession dispute broke out within the Guelders-ruling House of Egmont between Arnold, Duke of Guelders (died 1473) and his son Adolf, Duke of Guelders, which Philip's son Charles the Bold exploited to seize Guelders in 1473.
The Guelders Wars erupted in 1502 due to an old disagreement that had not been resolved. The Second War of the Guelderian Succession (1423–1448) ended with Gerhard VII, Duke of Jülich-Berg relinquishing his claims to the Duchy of Guelders to Philip the Good, Duke of Burgundy. A long-lasting succession dispute within the Guelders ruling House of Egmont between Arnold, Duke of Guelders (died 1473), and his son Adolf, Duke of Guelders, was exploited by Philip's son Charles the Bold to seize Guelders in 1473.
