Explanation

Forget prime ministers, presidents or even kings or queens: an emperor was the biggest, baddest ruler of them all — the leader of undisputed power who controlled a nation or, more usually, a number of subjugated nations known collectively as an empire. Nowadays the emperor is no more, replaced by humbler and usually more democratic leaders, but the notion of an all-conquering larger-than-life figure lives on in the way we give the prefix emperor to particularly magnificent specimens of living things: the Emperor Butterfly, Emperor Moth and Emperor Penguin, most famously. The Roman emperors would be proud.
