Gelderland
Gelderland, the largest and one of the oldest Dutch Provinces, has a flag, adopted 13 April 1953, with colours based on the arms: a golden lion on a blue field and a black lion on a golden field; this is based on the arms of the count of Gelre, early in the 13th century, featuring a golden lion on a blue field. In 1543 Charles V combined the lion of Gelderland with the lion of the town of Zutphen, a red lion with golden crown on a silver shield. This was changed in 1802 to the present arms.
