This video will explain how territory is divvied up on the Campaign Map, how to manage said territory and the garrisons that protect your lands.
Territory on the Campaign Map is divided into provinces, each province contains multiple settlements which can be attacked and controlled. Settlements are cities or ports on the map from which provinces are defended and controlled. Ownership of a settlement grants ownership of the territory around it. To attack a settlement, first select an army and then right-click on the desired target location.
To protect a settlement, the ruling faction may position an army inside to defend it from attack; settlements also produce their own garrison army which will automatically defend it when attacked. These armies have no upkeep cost, but can be depleted by repeated battles.
Although a faction may expand and capture any settlement, some are located in climates unsuitable for your faction to colonise, causing slower growth and a variety of other penalties. Plan your expansions accordingly! Around an army or settlement is a zone of control: enemies cannot pass through these, except to attack the owner. This can come in useful when protecting a settlement, placing an army at a potential pathway to it would force any would-be attacker to engage the army first.
Buildings may be constructed within a settlement by the faction that controls it to boost its production capabilities or defences – construction and repair options may be browsed on the Province Overview panel. For more information on buildings and their uses, check out our video on buildings in the campaign.
