Abington the 2nd

From BattleMaster Wiki

A short-lived secession of the duchy of Stoneville from the kingdom of Suville. Started out on the last days of August 2008, lost the city back to Suville forces 2½ weeks later, mid-September.

The countryside regions rejoined Suville the day after the split was done, leaving the stub of a new realm with less than half a dozen nobles and no food supply. The "new Abington" was met with hostility from the whole realm neighborhood, and was constantly plagued by anarchy during its short lifespan.

Didn't have a banner nor much of regional possessions apart from the city itself.
