Teddy/Bull Moose, I got a culture win on Emperor Level, but I don't remember how many turns it took. It was early 1900s though.
Didn't have to fight a lot of wars to get their either. I did have to stomp out the Khymer religion when they wouldn't stop converting my cities, though
Currently giving the Aztecs a whirl to see how it goes. I'm playing the shuffled tech/culture trees + secret societies
