Eccentric stars who made history (5)
I believe the answer is:
tsars
'who made history' is the definition.
I can't judge whether this defines the answer.
'eccentric stars' is the wordplay.
'eccentric' is an anagram indicator.
'stars' with letters rearranged gives 'TSARS'.
Can you help me to learn more?
(Other definitions for tsars that I've seen before include "Old Russian rulers" , "Old monarchs" , "Russian emperors" , "Old Russia's rulers" .)
