Civil War And How to Prevent It

[Satyr]

My simple guide:

1. Make your emperor with Magnificent Builder
2. Low taxes

My guide:

1. Rule the seas - so you never lose control and make massive revenue
2. Autotax - aim for Highest taxes in all provinces

I also make all my Governors, either ex-princes, after a new king is crowned or assign to new "Royal Knights". These units have the highest loyalty. If one does have lower loyalty I then have one of daughters marry him.

I have inflicted civil war on the Byzantines (Early) before. It required me to take massive amounts of their territory in a short time to reduce the Emperor's influence enough to trigger it (often via massive naval invasions). However, by the time civil war erupts, they were too weak to pose any threat to me.

The Byzantine has a higher than normal starting factor for their influence. Add in ingame events that add to their influence and you get monster Emperors and princes.
