The Diplomacy System Explained
Diplomacy in Anno 117 is your way to communicate through problems instead of resolving everything with swords. Once you reach the negotiation screen, you get a complete overview of all diplomatic options available. Actions that you can take appear at the top. Locked options are at the bottom and give you a hint of what you need to unlock them.

Hover over an action to learn why a governor might accept or reject it. The game displays all the reasons influencing their decision. This includes:
- Personal preferences like hygiene or belief
- Recent events that changed the mood
- Existing treaties you already signed
- Character traits
- Your prestige score
- Your military strength
These details help you understand what your rivals value. If someone keeps refusing your offer, you know exactly what to improve. Maybe you need more prestige. Maybe you signed a treaty they dislike. Or perhaps your army appears weak, and they sense easy land. Click on any active option to see a detailed breakdown before confirming it. This allows you to identify the risks beforehand.

Diplomacy offers several powerful tools. Trade treaties grant access to goods. Defensive pacts deter bullies. Alliances provide long-term support and can completely shift the balance of power. Some actions require research first, such as Large Gifts or high-level alliances. Others depend on your relationship with the Emperor. One example is appointing a rival governor as a specialist.
All of this constitutes one of the three main political pillars in Anno 117. Along with imperial favor and cultural choices, diplomacy shapes your campaign, borders, and identity. Every decision prompts a reaction. Every treaty opens up new opportunities or creates new problems.
How to Get More Prestige in Anno 117
Prestige is the foundation of every serious diplomatic move in Anno 117: Pax Romana. Without it, your rivals see you as just a newcomer. With it, they start listening, accept better deals, and stop trying to dominate you. High prestige makes advanced negotiations smoother and is crucial if you want to make rivals your vassals. A low score does the opposite: you get worse treaty terms and fewer options, regardless of how friendly you appear.

So you need to increase this attribute early and keep it growing. Luckily, there are several reliable ways to do that:
- Build prestige-focused structures: The easiest boost comes from the Governor Villa and various ornaments. They may look like decorations, but they are powerful prestige tools. Fill tight gaps in your layout with ornaments to maximize extra points.
- Advance your resident tiers: High-tier buildings unlock new structures with natural prestige bonuses. This occurs later in the game, but the payoff is significant. As your city’s status increases, prestige will rise naturally along with it.
- Use research strategically: Some upgrades directly boost prestige. A good example is Imperial Parades. This research increases prestige in the area around your Barracks and makes your city center stand out.
- Keep your attributes in good shape: When your city faces unrest, fires, or disease, its prestige drops. Ensure strong health, happiness, and fire safety. If these decline, you’ll spend more time repairing buildings and the city’s appeal diminishes.
- Appoint specialists: Certain specialists enhance prestige within your territory. Monitor new arrivals and assign them to where they can have the greatest impact.
Rivals and Vassals
Rivals are more than just annoying neighbors in Anno 117: Pax Romana. They can become valuable allies if you play your cards right. Turning a hostile governor into a loyal vassal can bring you serious rewards.

To subjugate a rival, you need real power. The game offers two possible paths:
- Strong alliance plus superior strength: Form an alliance with your rival and complete their personal quest chain. Once they trust you and you clearly outmatch them, the option to subjugate becomes available.
- Imperial authority and a full treasury: If the Emperor grants you the title of proconsul, your path becomes easier. You only need to be stronger than your rival and have a significant amount of money prepared.
Once you meet the requirements, you can demand their submission. If they accept, everything shifts quickly. Their islands instantly become vassal cities. Their fleet turns into yours. And the former rival joins your villa as a powerful specialist.
Vassals behave like semi-independent partners. They send you consistent gold through tribute and support you in military conflicts. This allows you to gain influence without the hassle of managing every island yourself.
But vassals are not mindless. They remain loyal only as long as you stay strong. If your prestige or military power falls, they might reconsider their loyalty. Neglect them too long, and rebellion becomes a real threat.
Diplomatically, subjugation falls between peace and outright conquest. It has moderate short-term costs and significant long-term benefits. You extend your influence without destroying your empire. Just remain alert. A vassal is a gift as long as you keep them satisfied.
