You there. Yes, you. Stop laughing. Poetry is serious and I am serious poet. This is Petar II Petrovic Njegos (a fact I divined by googling the dates on the bill with "Yugoslavia"), and he's described as "a Serb Orthodox Prince-Bishop." Says Wiki:

"Up to 1832, Petar fully cancelled governorship, therefore affirming full power over Montenegro. Petar II renamed the Praviteljstvo suda into Praviteljstvujušći sovjet, expanding its powers from just courtial to also management."
