Where Minos ruled (5)
I believe the answer is:
'where minos ruled' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crete that I've seen before include "Major island south of Greece" , "Greek island, site of the Minoan civilisation" , "Large Greek island" , "Knossos island" , "Greek territory" .)
