Diplomatic reputation in Europa Universalis IV (EU4) is a measure of how other countries perceive and trust your nation’s actions and words in diplomatic relations. A high diplomatic reputation can help your country in many ways, such as gaining allies, forming coalitions, and negotiating better deals in diplomacy.

How to Increase Diplomatic Reputation

To raise your diplomatic reputation in EU4, you can do the following:

Have a stable government

Stability is one of the most important factors affecting your diplomatic reputation in EU4. Your stability level reflects how well your government is functioning and how secure your nation is from internal turmoil. A high stability level makes other countries view you as a reliable and trustworthy partner in diplomacy. To raise your stability, you can:

  • Invest in stability improvements: You can spend administrative power to increase your stability level by one point, up to a maximum of +3 stability. You can also use decisions or events that provide stability bonuses.
  • Avoid disasters: Disasters can significantly decrease your stability level and damage your diplomatic reputation. Try to avoid triggering disasters by paying attention to your country’s unique triggers and taking preventive measures.
  • Keep your ruler and heir alive: The death of your ruler or heir can cause instability and increase the likelihood of a succession crisis. Make sure to have a stable line of succession and take steps to prevent untimely deaths.

Engage in diplomacy

Active engagement in diplomacy is a key way to improve your diplomatic reputation in EU4. By forming alliances, improving relations, and sending gifts, you can demonstrate your commitment to peaceful diplomacy and gain trust and respect. To engage in diplomacy, you can:

  • Form alliances: Alliances provide military support and a guarantee against aggression from other countries. They can also improve your diplomatic reputation by showing that you have trustworthy allies.
  • Improve relations: You can improve your relations with other countries by sending diplomats, using diplomatic actions, and completing missions. Improving relations can make it easier to negotiate with other countries and gain their support.
  • Send gifts: Sending gifts to other countries can improve their opinion of you and increase the likelihood of forming alliances or gaining their support in diplomatic deals.

Fulfill your promises

Making promises to other countries is a common practice in diplomacy. Promises can take the form of treaties, agreements, or other diplomatic deals. However, breaking your promises can damage your diplomatic reputation and make it harder to negotiate with other nations in the future. To avoid this, try to:

  • Only make promises you can keep: Think carefully before making a promise and consider if you can realistically fulfill it. Avoid overpromising to gain temporary benefits.
  • Honor your treaties and agreements: Once you make a promise, stick to it. Breaking a treaty or agreement can make other countries view you as untrustworthy and unreliable.
  • Use diplomatic feedback: When making deals, pay attention to the tooltip that shows how the other country feels about the proposed agreement. If the tooltip shows a negative response, consider renegotiating or finding another way to improve relations.

Maintain a strong army and economy

Having a strong military and economy can help improve your diplomatic reputation. A strong military can deter aggression from other countries, while a strong economy can make you a reliable trading partner and provide financial stability. To maintain a strong army and economy, you can:

  • Build up your economy: Invest in infrastructure, trade, and production to improve your economic strength. A strong economy can provide a stable foundation for your country and make you a more attractive partner in diplomacy.
  • Invest in military technology and units: Keep your military up to date with the latest technology and units to maintain a strong defensive capability. You can also invest in offensive units to project power and deter aggression.

Avoid aggressive behavior

Aggressive behavior, such as declaring war or conquering other countries, can damage your diplomatic reputation in EU4. Other countries may view you as a threat and hesitate to ally with you or form agreements. To avoid aggressive behavior, you can:

  • Use diplomacy to resolve conflicts: Try to resolve conflicts with other countries using diplomacy rather than force. Negotiate treaties, offer concessions, or use other diplomatic tools to find mutually beneficial solutions.
  • Avoid aggressive expansion: Aggressive expansion refers to the acquisition of territory through military conquest or forced annexation. This can be viewed as aggressive behavior by other countries and damage your diplomatic reputation. Instead, focus on peaceful expansion through colonization, vassalization, or other diplomatic means.
  • Respect other countries’ sovereignty: Treat other countries as equal partners in diplomacy and respect their sovereignty. Avoid interfering in their internal affairs or exerting undue pressure to gain concessions.

Complete diplomatic missions

Completing diplomatic missions is another way to improve your diplomatic reputation in EU4. Diplomatic missions provide specific objectives and rewards for achieving them, such as improving relations or forming alliances. To complete diplomatic missions, you can:

  • Select and complete missions: Choose missions that align with your diplomatic goals and work to achieve their objectives. Completing missions can provide immediate and long-term benefits for your country.
  • Use advisors and ideas: Some advisors and ideas can provide bonuses to diplomatic reputation or improve your ability to complete diplomatic missions. Consider investing in these options to boost your diplomatic efforts.
  • Monitor your progress: Keep track of your progress toward completing diplomatic missions and adjust your strategy as needed. By staying on top of your diplomatic efforts, you can continue to improve your reputation and secure your country’s place in the global community.


Diplomatic reputation is an essential aspect of the EU4 gameplay that can greatly impact your ability to achieve diplomatic success. By focusing on actions that can increase your reputation, such as honoring agreements, maintaining positive relationships with other nations, and developing skilled diplomats, you can build a reputation that will make it easier to negotiate treaties, form alliances, and engage in diplomacy with other nations.

By following these tips, you can become a diplomatic powerhouse in the world of EU4 and lead your nation to greater success.
