I need to express the concept of "world leaders" (i.e. all the various heads of state, spoken of collectively). What would be the best way to do this?
Suet. Ner. 36_1 dixit:Nec minore saevitia foris et in exteros grassatus est. Stella crinita, quae summis potestatibus exitium portendere vulgo putatur, per continuas noctes oriri coeperat
Yeah, and in addition to that dux is a very general term for "leader", whereas if you want to relate the modern sense of "heads of state", you might have to get a bit creative; no single existing term seems able to convey that meaning. I think of a modern head of state more in terms of being an administrative and political leader, a chief executive, than a "ruler" per se. With this in mind, you might have praefecti politiarum ("those who have been put in charge of the states")? Alternatively, you might have principes politiarum (saeculores). If you don't mind a Late Latin term, you might have officiarii principales politiarum.to me that implies that the person/people in question are leaders of the entire world, whereas I meant more like individual heads of state.
