Biography
Arnold, Duke of Guelders, is remembered less for peaceful rule than for a devastating family feud that defined his era. Inheriting the duchy as a child, his early reign was managed by regents, including the powerful Duke of Burgundy, Philip the Good. This Burgundian influence would shape his destiny. Arnold's troubles crystallized around his son, Adolf, who chafed under his father's rule and financial mismanagement. In 1465, Adolf rebelled, plunging Guelders into a civil war that lasted nearly a decade. The conflict saw Arnold captured, ransomed, and repeatedly deposed and restored, with both father and son becoming pawns in the wider power struggle between Burgundy and France. In the end, Arnold was forced to mortgage his duchy to Charles the Bold of Burgundy to pay his debts, a move that ultimately led to Burgundian control, ending his line's independent rule in a saga of personal and political failure.
