Diplomacy & Trade

Secure victory in Total War: Warhammer III with savvy Diplomacy and Trade. Build alliances, protect borders, and generate income to outmaneuver foes.

Diplomacy and trade are often overlooked but crucial aspects of securing victory in Total War: Warhammer III. A strong diplomatic network can provide vital allies, secure your borders, and generate significant income, allowing you to focus your military might where it's truly needed. Neglecting diplomacy can leave you isolated and vulnerable to multiple fronts.

Understanding Diplomatic Stances

Your diplomatic stance with other factions is displayed in the Diplomacy screen, accessible via the scroll icon in the bottom right corner of your UI. Each stance has implications for potential interactions:

• War: You are actively fighting this faction. Your armies can attack theirs, and vice-versa.
• Neutral: No formal agreements, but no active conflict. This is the default stance with most newly encountered factions.
• Non-Aggression Pact: An agreement not to attack each other. This is a good first step towards improving relations.
• Trade Agreement: Allows both factions to exchange goods, generating income for both parties. Requires a Non-Aggression Pact first.
• Defensive Alliance: If one ally is attacked, the other is called to war. A strong commitment, but can drag you into unwanted conflicts.
• Military Alliance: The strongest form of alliance. Both factions will join each other's wars, and can even recruit units from allied territories (though this is more common in multiplayer campaigns).
• Vassal: A weaker faction that pays tribute to you and is automatically drawn into your wars. You gain control over their diplomatic decisions.
• Confederation: The ultimate diplomatic goal. The allied faction is absorbed into your empire, and you gain control of all their settlements, armies, and lords.

Building Diplomatic Relations

Improving relations with other factions is key to forging alliances and trade deals. Here's how to do it:

1. Send Envoys: Certain Legendary Lords or Heroes may have skills or traits that improve diplomatic relations. Actively using these characters in the vicinity of target factions can provide a passive boost.
2. Offer Gifts: In the Diplomacy screen, you can offer gold or resources as a gift to a faction. This provides an immediate, though temporary, boost to relations. Use this strategically to push a faction over the threshold for a desired agreement.
3. Fight Common Enemies: Attacking a faction that your target also dislikes will naturally improve your relations with them. This is often the most organic way to build goodwill.
4. Honor Treaties: Always uphold your Non-Aggression Pacts and Alliances. Breaking treaties incurs a significant diplomatic penalty with all factions, making future agreements much harder to secure.
5. Avoid Trespassing: Moving your armies through another faction's territory without a Military Access treaty will incur a minor diplomatic penalty.

Securing Trade Agreements

Trade Agreements are a cornerstone of a healthy economy. They provide a consistent income stream and are relatively easy to secure once you have a Non-Aggression Pact.

• Prerequisites: You must have a Non-Aggression Pact with the target faction. You also need to have a land connection or a port connection to their territory.
• Initiating Trade: Open the Diplomacy screen, select the desired faction, and click "Propose Deal." Select "Trade Agreement" from the available options.
• Evaluating Trade Value: The game will show you the estimated income you will receive per turn from the trade agreement. This value is influenced by the number of unique resources each faction possesses. Prioritize trade with factions that have resources you don't, and vice-versa.
• Resource Management: Building resource-producing structures in your settlements (e.g., Iron Mine, Gem Mine, Spice Trader) will increase the value of your trade agreements.

Forging Alliances

Alliances provide military support and can deter aggressive neighbors. However, they also come with risks.

• Defensive Alliance: A good stepping stone. It provides a sense of security without fully committing to every conflict. Aim for these with factions bordering your enemies or those you wish to protect.
• Military Alliance: The strongest bond. This is ideal for factions you intend to confederate later or those that share a long-term strategic objective. Be prepared to join their wars, as refusing will severely damage your reliability and diplomatic standing.
• Call to Arms: When an ally is attacked, you will receive a "Call to Arms" notification. You have a limited number of turns to accept or decline. Accepting will declare war on their attacker; declining will incur a diplomatic penalty.
• Coordinated Attacks: Once allied, you can use the "Coordinated Attack" option in the Diplomacy screen to request an ally to attack a specific enemy settlement or army. This can be invaluable for breaking sieges or overwhelming a strong foe.

Confederation Strategy

Confederation is the most powerful diplomatic tool, allowing you to absorb an entire faction into your empire. This grants you their settlements, armies, and lords, significantly expanding your power base.

• High Relations are Key: You generally need very high diplomatic relations (typically +150 or more) with the target faction.
• Shared Enemies: Actively fighting common enemies with the target faction will significantly boost their willingness to confederate.
• Power Disparity: The target faction is more likely to confederate if they are significantly weaker than you, especially if they are under threat from other factions.
• Offer Gold: Sometimes, a large sum of gold can be the final push needed to secure a confederation, even if relations aren't at their absolute peak.
• Legendary Lord Specifics: Some Legendary Lords have unique confederation mechanics. For example, Karl Franz of the Empire can confederate other Elector Counts through specific quests or events. Always check your faction's unique mechanics for easier confederation opportunities.
• Post-Confederation Management: Be prepared for a potential public order hit in newly acquired territories. Ensure you have sufficient armies to maintain control and integrate the new regions effectively.
