Old king wildly threatened with large axe briefly (9,3,5)

I believe the answer is:

alexander the great

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

'old king wildly threatened with large axe briefly' is the definition.
I can't judge whether this definition defines the answer.

'wildly threatened with large axe briefly' is the wordplay.
'wildly' indicates an anagram.
'with' means one lot of letters go next to another.
'briefly' means to remove the last letter.
'large'+'axe'='largeaxe'
'largeaxe' with its final letter taken away is 'largeax'.
'threatened' after 'largeax' is 'largeaxthreatened'.
'largeaxthreatened' is an anagram of 'ALEXANDER THE GREAT'.

Can you help me to learn more?

(Another definition for alexander the great that I've seen is " world ruler".)

I've seen this clue in The Times.
