Adolf was the son of
Arnold, Duke of Guelders and
Catherine of Cleves. In the battle of succession for
Guelders, he imprisoned in 1465 his own father and became Duke with the support of
Philip the Good, who also made him Knight in the
Order of the Golden Fleece. In 1468, he won the Battle of Straelen against Cleves, but
Charles the Bold reinstated his father Arnold, and Adolf was imprisoned in
Hesdin. After the death of Charles the Bold in 1477, Adolf was liberated by the
Flemish. He died the same year at the head of a Flemish army besieging Tournai, after the States of Guelders had recognized him as Duke. His body was buried in
Tournai Cathedral. ==Family and issue==
