Byzantine

The Byzantine Empire, sometimes called the Swiss-Byzantine Empire, was founded and run by RoryIsK

The empire was founded by Rory, inherited several vassals with war, taking control of the Swiss by a political union over them (due to the Swiss leader being inactive). Later, due to the warmongering and supposed unsuitability of the leader, several key members left from the faction, leading to multiple wars for the Byzantine Empire losing lots of manpower, equipment and getting in several fatal wars, before the leader simply gave up and the entire table was destroyed.
