I believe the answer is:

renascence

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

'revival' is the definition.
(renascence is a kind of revival)

'unsettled near uproar about conservative' is the wordplay.
'unsettled' indicates an anagram.
'uproar' becomes 'scene' (I can't explain this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'conservative' becomes 'C' (UK political abbreviation).
'scene' enclosing 'c' is 'scence'.
'near' anagrammed gives 'rena'.
'rena'+'scence'='RENASCENCE'

Can you help me to learn more?

(Another definition for renascence that I've seen is " Revival of something dormant".)

I've seen this clue in The Independent.
