Medieval communism

Paradox sloppiness keeps delivering:

while shuffling around assets in my Ruthenia play, to my GREAT amuzement I've discovered a city of Pervomaysk, which is as hardcore Soviet Communist name as it ever could be (literally means 'The city named after the 1st May aka International Labor Day'). That's even more entertaining than a previous name 'Kuzbass - Kuznetsk Coal Bassin' I discovered in Siberia.

For all Paradox groupies in the comments - even simpliest googling shows there was an original town in 18th century.
