Your Majesty, I recommend ensuring internal peace by addressing the needs of your citizens, such as food, justice, and security. Establish a fair legal system, appoint wise advisers, and invest in infrastructure. To avoid conflicts with neighboring nations, foster diplomatic relations, engage in fair trade practices, and occasionally negotiate mutual defense pacts with allies.
Imagine you are an adviser to a medieval king. What advice would you give him to maintain peace within the kingdom and avoid conflicts with neighboring nations?
