When should "Dictator" be capitalized?

I'm wondering whether the word dictator should be capitalized.

Is it just an adjective and not an (official) title?


Solution 1:

It depends on context and preference. If used as a noun, it's not capitalised:

He was the dictator of Sicily.

If used as a title, it ought to be:

He proclaimed himself Dictator of Sicily.

And also if used as an honourific:

He was called Dictator Garibaldi.
