Rebels

Rebels are the generic term used to refer to all units, settlements and agents without an owner.

Features
Rebels are considered to be a faction, though they differ from standard factions in various ways: Rebels do not recruit units, build structures or attempt to expand over other factions. They cannot enter diplomatic relations, and are permanently at war with all other factions.

When a settlement has low public order, usually lower than 70%, rebellion will occur. When a settlement rebels, its garrison will be forcibly ousted and replaced with a rebel army.

There are also various brigands that represent thieves, robbers and other disruptive influences in a province. They will appear inside territories and regions under control of other factions.

Rebel Factions
The "Rebels" Faction is divided into numerous subfactions -these factions are largely aesthetic but also determine what rebel units will spawn in a region.
