Prince
BZZZ, wrong.
The title is affected by the Policy Tree you choose, for example Doge will appear if you focus on Commerce, while Consul will appear if you focus on Liberty. Pious will appear if you select and focus on Piety.
I say focus because it doesn't matter how many policies you chose per tree, if you keep choosing Piety despite having Tradition fulfilled you will eventually become Pious, but I believe after a while it will go back to Tradition's title.
Oh you mean the social policy ones. I thought me he meant the end game ranks like Ivan the Terrible since thats not a character in the game nor a rank. But your description is correct about those titles.
