Roman Kingdom of Italy

The Roman Kingdom of Italy (RKI) is a Roman faction that usually gets its first core in the mid-400s. It loses all its cores in 474, making it one of the shortest lived nations in the game.

Despite its low relative lifespan, the RKI is actually a fairly powerful nation due to it having cores on all of Italy and controlling all of it if you start in 476. Italy is one of the most developed regions in the game in the 400s, allowing the RKI to field a sizable army. However, it has a low max province count, so it's tough to play as unless one person sets down poor taxes to low/very low and focus on utilizing PP (Political Power) to supress rebel chance.
