A tale of monarchs and national anthems

Anyone who has watched a Scottish rugby or association football match will be familiar with the Corries’ folk song O Flower of Scotland, which is played before their matches. The second line of the chorus (“Proud Edward’s army”) refers to Edward II, defeated at Bannockburn so that he never actually ruled Scotland although he may have technically been their King by marriage. I have chosen Barbara Dickson’s version.

The Netherlands’ national anthem, the Wilhelminus, is named after William the Silent, a Protestant monarch assassinated in 1584 during an ongoing independence war against the Spanish forces. Paradoxically, perhaps, it is sung lustily among a sea of orange flags at football internationals.

Can you think of any other monarchs mentioned in anthems?
