Total War: Rome II diplomacy, sieges and campaign movement
Choose wars and assaults that the campaign economy can sustain.
Edition covered
Rome II (2013) using the current Emperor Edition PC release. Emperor Edition includes the later Imperator Augustus campaign; this guide focuses on the Grand Campaign and shared systems. DLC factions and campaigns are separate.
Check diplomacy before adding another enemy

Trade, non-aggression and other agreements affect the strategic map. Read obligations and relationships before attacking a convenient target that could create multiple fronts.
| Agreement or condition | Question | Planning effect |
|---|---|---|
| Trade agreement | Is trade viable and useful? | Supports the economy |
| Non-aggression | Are you planning to attack this neighbor? | Avoid conflicting commitments |
| Alliance | What wars could it involve? | Assess obligations before accepting |
| War declaration | How many fronts can you hold? | Keep the campaign manageable |
Prepare a siege army for the actual settlement
Walls, entrances and defended streets require a different plan from an open field. Bring suitable siege tools and enough infantry to secure a breach without funneling every unit through one lethal point.
| Concern | Preparation | Purpose |
|---|---|---|
| Walls and gates | Suitable siege equipment or an assault plan | Create a usable entry |
| Defended streets | Reserve infantry and missiles | Avoid one congested push |
| Nearby enemy armies | Inspect reinforcement potential | Prevent a surprise larger battle |
| After capture | Food, order and repair reserve | Hold the settlement you won |
Use the campaign map to isolate a target
Position supporting armies and inspect reinforcement ranges before committing. A battle against one visible army can include nearby forces if you ignore the surrounding map.
Monitor internal stability while campaigning
Long wars consume money and attention. Keep checking provincial order and the political interface so an external advance does not hide an internal crisis.
