In War Kingdoms, a colony is a small settlement that is under the rulership of a kingdom. The ruling kingdom may have established the colony or taken it from another kingdom. Colonies are conquerable settlements and can not be plundered. Colonies provide economic advantage to kingdoms by providing some amount of hourly gold gain.
A kingdom can establish only one colony throughout the game, but can own limitless number of colonies. To establish a colony, the only requirement that must be met by players is advancing to the Iron (2nd) Age. A colony can be built at any Unoccupied Place found on the map. However, there is a distinct advantage in having colonies close together and nearby to the kingdom center: sending armies is much quicker.
A colony does not earns its ruling kingdom a fixed amount of gold per hour. The minimum gain of a colony is 100 golds/hour. However, if the ruler deploys at least 100 military units to the colony, the colony reaches its maximum gain of 500 golds/hour.
