Beyond the Sword is the second expansion for Civilization IV, released in July 2007, and it is still the version most long term Civ 4 players run. It bolts three systems onto the 2005 base game: seven corporations that convert spare resources into food, production or cash, a full espionage economy with its own commerce slider, and the Apostolic Palace, a religious voting body that can hand you a diplomatic win centuries before the United Nations exists. It also brings ten new civilisations, six new leaders for existing ones, twenty five units, and eleven scenarios ranging from a squad tactics mission against the undead to a space colonisation mod.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.

New player? Start with Byzantium under Justinian I. See our beginner's guide for why.
Babylon under Hammurabi
Babylon arrives with Beyond the Sword and leans on early defensive strength through the Bowman, an archer replacement that holds a hill city against far larger armies. It is the safest of the new civilisations to learn on because the early game is forgiving.
| Attribute | Detail |
|---|---|
| Tier | A |
| Playstyle | Sit safe behind Bowmen through the ancient era, expand steadily, and convert your protected core into a corporate economy after Corporation. |
| Best Equipment | Spy |
| Stat Priority | Early defence first, then commerce, then production |
| Core Gear | Bowman garrisons, the Garden unique building, early Great Merchant for a corporation headquarters later |
| Key Mechanic | Corporations |
Strengths

- Sit safe behind Bowmen through the ancient era, expand steadily, and convert your protected core into a corporate economy after Corporation.

- Focus on Corporations. It's this build's primary system
- Prioritize Spy as your first major upgrade
- See our full Babylon under Hammurabi build guide for the optimal gear progression
Byzantium under Justinian I
The Cataphract is a Knight replacement strong enough to build a whole medieval war plan around, which makes Byzantium the most direct of the new civilisations. Justinian rewards players who want to solve problems with cavalry before corporations even exist.
| Attribute | Detail |
|---|---|
| Tier | S |
| Playstyle | Take your neighbour's cities during the Cataphract window rather than teching past it, then settle into the captured land. |

Holy Roman Empire under Charlemagne
Charlemagne pairs the Landsknecht, which punishes enemy mounted units, with the Rathaus, which cuts city maintenance. That combination suits a wide empire that would otherwise choke on upkeep.
| Attribute | Detail |
|---|---|
| Tier | A |
| Playstyle | Expand wider than the maintenance curve normally allows, and let the Rathaus pay for the cities everyone else would have skipped. |
| Best Equipment | Cataphract |
| Stat Priority | Expansion first, then maintenance reduction, then military |
| Core Gear | Rathaus in every distant city, Landsknecht stacks against cavalry civilisations |

- Prioritize Cataphract as your first major upgrade
- See our full Holy Roman Empire under Charlemagne build guide for the optimal gear progression
Khmer under Suryavarman II
The Ballista Elephant is a War Elephant replacement that hits stacks rather than single units, which changes how medieval battles resolve. The Baray unique building supports the food heavy cities that make the elephants affordable.
| Attribute | Detail |
|---|---|
| Tier | B |
| Playstyle | Grow tall cities on Barays, then use Ballista Elephants against the packed defensive stacks the AI likes to build. |
| Best Equipment | Ballista Elephant |

| Core Gear | Ivory secured early for elephants, Baray in your food cities |

- See our full Khmer under Suryavarman II build guide for the optimal gear progression
Netherlands under Willem van Oranje
The Netherlands is the trading civilisation of the expansion, with the East Indiaman for naval commerce and the Dike for coastal production. It fits the corporate economy that Beyond the Sword adds better than any other new civilisation.
| Attribute | Detail |
|---|---|
| Tier | A |
| Playstyle | Play wide on the coast, run trade routes rather than wars, and found a corporation in your best commerce city. |
| Best Equipment | East Indiaman |
| Stat Priority | Commerce first, then coastal production, then military |

Which Build Should You Pick?
For Beginners
Byzantium under Justinian I is the clear winner. It's forgiving, teaches core mechanics, and remains competitive into endgame. Follow our beginner's guide for the best first-session experience.
For Maximum Performance
Babylon under Hammurabi is the top pick once you understand the game's mechanics. Pair it with Spy for the strongest overall setup.
For a Challenge
Netherlands under Willem van Oranje offers the highest skill ceiling. It's punishing when misplayed but incredibly rewarding when mastered. Only recommended after you've completed the game with another build.
For Group Play
Khmer under Suryavarman II shines in cooperative content with utility and team support capabilities.
