Cuban Croats, possibly? (6)

I believe the answer is:

castro

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

'cuban' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?

'croats possibly?' is the wordplay.
'possibly?' is an anagram indicator (I've seen 'possibly' mean this).
'croats' is an anagram of 'CASTRO'.

Can you help me to learn more?

(Other definitions for castro that I've seen before include "Cuban president (past and present)" , "Fidel . . . . . .,retired Cuban leader" , "Latin American dictator" , "Fidel ......, Cuban chief" , "Fidel or Ral" .)
