Great Holy Wars, such as Crusades and Jihads, represent the most significant religious conflicts in Crusader Kings III. These wars involve massive armies from across the globe and can result in the complete loss of kingdoms or the establishment of new crusader states. Defending against them requires a multi-faceted approach.
Understanding the Mechanics
Great Holy Wars are declared by the Pope or the Caliph against a ruler of a hostile faith. They are not just about conquering a single county but often aim to seize entire kingdoms or duchies. The war score is influenced by battles, sieges, and the capture of key characters.
Pre-War Preparations
The best defense against a Great Holy War is to prevent it from becoming overwhelming:
- Maintain Strong Faith Relations: A strong relationship with the Pope or your faith's religious head can sometimes prevent them from declaring a Great Holy War against you.
- Diplomatic Alliances: Forge alliances with powerful rulers of your faith. These allies will be called to join your defense and can bring significant military might.
- Economic Strength: Gold is paramount. You will need it to raise your own levies, hire mercenaries, and potentially bribe your way out of certain situations. Invest in your economy.
- Fortifications: Ensure your border duchies and counties have strong defensive buildings. Castles with high levels of walls and garrisons are essential.
- Men-at-Arms: Invest in Men-at-Arms that are effective against the likely attackers. For example, heavy infantry can be good against tribal levies, while archers can be useful against cavalry.
During the Great Holy War
When the declaration comes, act decisively:
- Consolidate Your Forces: Rally all your levies and allied forces. Avoid splitting your army into smaller, vulnerable groups.
- Target Enemy Leaders: The enemy commander is a high-value target. Attempting to capture or kill them can cripple their war effort.
- Defend Key Territories: The war goal will usually be a specific kingdom or duchy. Focus your defenses on these areas.
- Harass Supply Lines: If possible, use smaller, faster stacks to raid enemy supply lines and disrupt their sieges.
- Mercenary Reinforcements: Be prepared to hire additional mercenaries if your initial forces are insufficient.
- Negotiate if Necessary: If the war is going poorly and you cannot win, consider negotiating a white peace or surrendering to a less damaging outcome, especially if your ruler's life is at stake.
Post-War Recovery
After a Great Holy War, whether you won or lost, recovery is essential. Rebuild your armies, repair damaged holdings, and address any internal dissent that may have arisen due to the conflict.
Successfully navigating a Great Holy War is a testament to strong leadership, strategic planning, and a robust realm.
