Roman ruler in the outskirts of Turin? (6)

I believe the answer is:

trajan

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

'roman' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?

'ruler in the outskirts of turin?' is the wordplay.
'ruler' becomes 'raja' (historical term for an Indian king or prince).
'in the' indicates putting letters inside.
'outskirts of' means to remove the middle letters (only letters on the outskirts).
'turin' with its middle removed is 'tn'.
'raja' put inside 'tn' is 'TRAJAN'.

Can you help me to learn more?
