Holy Wars are a significant threat in Crusader Kings III, allowing hostile faiths to declare war on your realm with the goal of seizing territory or converting your counties. Effectively defending against these can be the difference between survival and subjugation.
Preparation is Key
The best defense is a strong offense, or at least a well-prepared defense. Before a Holy War is declared, consider the following:
- Maintain Strong Relations: Keep your vassals happy. Unhappy vassals are more likely to join factions, weakening your realm when you need it most.
- Fortify Borders: Invest in buildings that increase your levies and provide defensive bonuses in your border counties. Castles and walls are your best friends.
- Build Up Your Army: Ensure you have a healthy standing army and a good reserve of gold to raise mercenaries if needed. Consider investing in Men-at-Arms that are effective against your likely attackers.
- Diplomacy: Forge alliances with powerful rulers of your faith. These allies can be crucial in defending your realm.
During a Holy War
Once a Holy War is declared, swift action is paramount:
- Assess the Threat: Check the strength of the attacking army and their war goal. This will help you prioritize your defenses.
- Rally Your Levies: Immediately raise your levies and position them strategically. Avoid fighting outnumbered if possible.
- Target Enemy Leaders: If possible, try to assassinate the enemy leader. This can often end the war prematurely or significantly weaken their resolve.
- Defend Key Holdings: Focus on defending your most important castles and cities. Losing these can quickly erode your war score.
- Use Mercenaries Wisely: If you have the gold, hire mercenaries to bolster your forces. They can be decisive in key battles.
- Siege Defense: If the enemy manages to siege your holdings, ensure your garrisons are strong enough to hold out for as long as possible.
Post-War Considerations
After successfully defending against a Holy War, it's important to rebuild and learn from the experience:
- Replenish Levies: Your levies will be depleted. Take time to let them recover.
- Repair Holdings: Damaged holdings should be repaired to restore their defensive and economic benefits.
- Review Your Defenses: Analyze what worked and what didn't. Were your alliances strong enough? Did you have enough gold for mercenaries?
By being proactive and making smart decisions during the conflict, you can effectively repel Holy Wars and maintain the integrity of your realm.
