Pope upset the Parisian folk (6)
I believe the answer is:
people
'folk' is the definition.
(I know that people is a type of folk)
'pope upset the parisian' is the wordplay.
'upset' indicates an anagram.
'the parisian' becomes 'le' (definite article in French).
'pope' with letters rearranged gives 'peop'.
'peop'+'le'='PEOPLE'
(Other definitions for people that I've seen before include "Folk; citizens" , "Race - mankind" , "country folk" , "Mortals" , "Community" .)
