Aged drunk abused European royalty (5,4)

I believe the answer is:

grand duke

I'm a little stuck... Click here to teach me more about this clue!

'european royalty' is the definition.
'grand duke' can be an answer for 'royalty' (thesaurus). I am unsure of the 'european' bit.

'aged drunk abused' is the wordplay.
'abused' is an anagram indicator.
'aged'+'drunk'='ageddrunk'
'ageddrunk' with letters rearranged gives 'GRAND DUKE'.

Can you help me to learn more?

(Other definitions for grand duke that I've seen before include "prince" , "European nobleman" .)

I've seen this clue in the Sydney Morning Herald.
