Like an emperor, note, one Iran scrapped (8)

I believe the answer is:

neronian

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

'like an emperor' is the definition.
I know nothing about this answer so I can't tell whether this works.

'note one iran scrapped' is the wordplay.
'note' becomes 'n' (abbreviation).
'scrapped' is an anagram indicator.
'one'+'iran'='oneiran'
'oneiran' anagrammed gives 'eronian'.
'n'+'eronian'='NERONIAN'

Can you help me to learn more?
