A faction is a group of players who work together to achieve common goals. Joining a faction is an important first step into the vibrant political life of Stronghold Kingdoms and even new players can contribute to the faction’s success. Each faction has a leader, called the faction general (FG), who appoints officers and tends to the needs of the faction members. Once a faction has five or more members, it may apply for admission to a house.

If a faction's membership drops below five members, it will be automatically removed from a house if it was in one.

After a certain period of inactivity, players with no villages will be automatically removed from their faction.
