Territories are land tiles which make up the Kingdom Conquest world. Some territories are abandoned, while others are occupied by players or towers. Any territory can be conquered by a player as long as that territory is not a player's main fortress. To conquer a territory, the following criteria must be met:
- The player must already own a tile adjacent (the tile can be beside it or diagonal to it) to the target territory.
- The player must launch an attack (dispatch a unit) on the target territory, and they must defeat all monsters in battle.
- If the territory is owned by another player, or if it is a tower, then the player must destroy the territory before it can be conquered. This is done by repeatedly attacking the territory, causing damage (based on the unit's monsters' combined siege points). The amount of damage that must be inflicted is dependent on the territory's durability.
