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.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
Corporations
Seven corporations unlock from the Corporation technology, and each needs a specific Great Person, an extra technology and access to particular resources to found its headquarters. Cereal Mills turns Corn, Rice or Wheat into food from a Great Merchant, Mining Inc. turns Coal, Iron, Copper, Gold or Silver into production from a Great Engineer, and Standard Ethanol produces Oil from Corn, Sugar or Rice through a Great Scientist. Each can be founded only once per game, so the race for a corporation is as sharp as the race for a religion.
Espionage points and the espionage slider
Espionage becomes a real economy rather than a footnote, with a commerce slider that diverts output into espionage points accumulated separately against each rival. Spies infiltrate cities and run missions such as stealing a technology, sabotaging production, poisoning the water supply or inciting a revolt, and Great Spies add heavier options. Because points build against a specific target, the espionage game rewards picking one victim rather than spreading yourself thin.
The Apostolic Palace
The Apostolic Palace is a wonder tied to the state religion of whoever builds it, and every civilisation influenced by that religion gets votes. Resolutions cover holy wars, trade embargoes and forced peace, and a supermajority can award an outright diplomatic victory long before Mass Media brings the United Nations online. Defying a resolution is possible, which turns the Palace into a diplomacy trap rather than a rubber stamp.
Random events
More than a hundred events fire across a game, covering natural disasters, resource discoveries, diplomatic marriages and city specific opportunities. Some hand you a choice with a gold cost attached, others simply happen to a city you were relying on. They stop optimal openings from playing out identically every time, which is much of why Beyond the Sword still gets played.
Advanced Start
Advanced Start gives you a budget to spend on cities, buildings, units and technologies before turn one, so you can begin a game in any era with a developed nation. It exists to skip the parts of the early game that experienced players find repetitive, and it is the fastest way to practise a midgame or lategame position directly.

Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Babylon under Hammurabi | A | Sit safe behind Bowmen through the ancient era, expand steadily, and convert your protected core into a corporate economy after Corporation. | Early defence first, then commerce, then production |
| Byzantium under Justinian I | S | Take your neighbour's cities during the Cataphract window rather than teching past it, then settle into the captured land. | Production first, then military technology, then commerce |
| Holy Roman Empire under Charlemagne | A | Expand wider than the maintenance curve normally allows, and let the Rathaus pay for the cities everyone else would have skipped. | Expansion first, then maintenance reduction, then military |
| Khmer under Suryavarman II | B | Grow tall cities on Barays, then use Ballista Elephants against the packed defensive stacks the AI likes to build. | Food first, then production, then military technology |
| Netherlands under Willem van Oranje | A | Play wide on the coast, run trade routes rather than wars, and found a corporation in your best commerce city. | Commerce first, then coastal production, then military |
Babylon under Hammurabi (A-Tier): 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.
Byzantium under Justinian I (S-Tier): 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.
Holy Roman Empire under Charlemagne (A-Tier): 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.
Khmer under Suryavarman II (B-Tier): 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.
Netherlands under Willem van Oranje (A-Tier): 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.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Spy | The espionage workhorse, moving into rival territory to infiltrate cities and spend accumulated espionage points on missions. | Players who want to keep pace in technology without out-researching a runaway AI. |
| Executive | The corporate equivalent of a Missionary, spreading your corporation into a city so it starts consuming resources and producing its bonus there. | Expanding a founded corporation into cities that actually have the input resources nearby. |
| Cataphract | The Byzantine Knight replacement and one of the strongest medieval units in the expansion. | A medieval war of conquest launched before crossbows and pikemen become common. |
| Ballista Elephant | The Khmer War Elephant replacement, which damages an entire enemy stack rather than only the defender. | Breaking large defensive stacks before you commit your main melee units. |
| East Indiaman | The Dutch naval trade unit, tuned for commerce rather than for winning sea battles. | Coastal Dutch empires playing for economy instead of early conquest. |
Spy: The espionage workhorse, moving into rival territory to infiltrate cities and spend accumulated espionage points on missions. Missions range from stealing a technology to poisoning a water supply, and a caught spy can start a war you were not ready for.
Executive: The corporate equivalent of a Missionary, spreading your corporation into a city so it starts consuming resources and producing its bonus there. Corporations cost gold per city they operate in, so spreading everywhere is not automatically correct.
Cataphract: The Byzantine Knight replacement and one of the strongest medieval units in the expansion. It is powerful enough that Justinian games often revolve around whether you used its window or wasted it.
Ballista Elephant: The Khmer War Elephant replacement, which damages an entire enemy stack rather than only the defender. Against the AI habit of piling units onto one tile, that is a very efficient answer.
East Indiaman: The Dutch naval trade unit, tuned for commerce rather than for winning sea battles. It fits a Netherlands game that funds itself through trade routes and later through a corporation.

Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Afterworld | Standalone tactical scenario | Squad tactics practice, a complete change of pace from the main game |
| Broken Star | Modern era scenario | Fast paced modern warfare without a long buildup |
| Charlemagne | Dark Ages Europe scenario | Coronation as Holy Roman Emperor, religious diplomacy practice |
| Final Frontier | Space era total conversion | Star system colonisation, a completely reworked tech tree |
| Next War | Near future scenario | Extended future technologies, late era unit variety |
Afterworld: A squad based tactical scenario against the undead with no city building at all, closer to a turn based skirmish game than to Civilization. It is the clearest demonstration of how far the Civ 4 engine could be pushed by the scenario tools.
Broken Star: Opens with Russia in civil war, so you begin fighting for control of a fragmenting state rather than founding a capital. It is one of the tighter scenarios because the starting position already contains the conflict.
Charlemagne: You conquer Dark Ages Europe while courting the Pope, and enough papal favour sees you crowned Holy Roman Emperor. It ties the expansion's religious diplomacy directly into a conquest objective.
Final Frontier: A science fiction mod where you explore and settle star systems while looking for the route home to Earth. Systems replace terrain and starships replace armies, which makes it the most transformed of the eleven.
Next War: A near future scenario built around clone armies, cyborgs and other technologies past the base game's modern era. It extends the tech tree rather than replacing it, so the familiar rules still apply.

Tips That Actually Matter
- Found a corporation only when you already control the input resources, because a corporation with nothing to consume still charges you maintenance in every city it reaches.
- Sid's Sushi Co., Cereal Mills and Standard Ethanol all consume Rice, so you cannot run all three in the same city and should decide which one your empire actually needs.
- Standard Ethanol produces Oil from Corn, Sugar or Rice through a Great Scientist headquarters, which is the peaceful answer to having no Oil on your continent.
- Espionage points accumulate separately against each rival, so pick one target and drive points into that relationship rather than spreading effort across the board.
- Poisoning a water supply or sabotaging production is often cheaper than fielding an army against a city you only need slowed down.
- Either build the Apostolic Palace yourself or make sure it goes to a civilisation whose religion you share, because votes follow religious influence and being outside the majority means being outvoted.
- Resolutions can be defied rather than obeyed, so treat the Apostolic Palace as a diplomatic pressure tool rather than a set of binding laws.
- Advanced Start lets you buy cities, buildings, units and technologies before turn one, which is the fastest way to practise a specific era instead of replaying the opening every time.
- Random events fire more than a hundred different ways, so keep some gold in reserve for the ones that offer a paid choice rather than a fixed outcome.
- The space victory now requires reaching Alpha Centauri rather than only launching, so a faster ship built later can still beat a slower ship launched first.
Common Mistakes to Avoid
- Spreading a corporation into every city with an Executive without checking whether those cities have the input resources or the gold to carry the maintenance.
- Running the espionage slider at a high rate while splitting points across every rival, which produces nothing usable against any single target.
- Letting a rival build the Apostolic Palace while you sit outside its religion, then losing votes on resolutions that directly affect your wars.
- Founding Cereal Mills and Sid's Sushi Co. in the same city and wondering why they compete rather than stack, since both consume Rice.
- Treating Beyond the Sword like Civilization VI, where corporations, the espionage slider and Apostolic Palace voting simply do not exist in the same form.
Frequently Asked Questions
Do I need the base game and Warlords to play Beyond the Sword?
You need Civilization IV. Beyond the Sword is the second expansion, released in July 2007 after Warlords, and it is the version most veteran players still run because it contains corporations, the espionage economy and the Apostolic Palace.
Which corporations are worth founding?
It depends on what your empire already owns. Mining Inc. turns Coal, Iron, Copper, Gold or Silver into production, Cereal Mills turns Corn, Rice or Wheat into food, and Standard Ethanol produces Oil from Corn, Sugar or Rice. Each of the seven can be founded only once in a game, and each needs a specific Great Person.
What civilisations were added?
Ten: Babylonia, the Byzantine Empire, the Ethiopian Empire, the Holy Roman Empire, the Khmer Empire, the Mayans, the Native Americans, the Netherlands, Portugal and Sumer. Six leaders joined existing civilisations, including Abraham Lincoln, Charles de Gaulle, Boudica, Darius I, Suleiman the Magnificent and Pericles.
How does the Apostolic Palace win work?
The Palace is tied to the state religion of whoever builds it, and civilisations influenced by that religion receive votes. Resolutions cover holy wars, embargoes and forced peace, and a supermajority can award a diplomatic victory long before Mass Media unlocks the United Nations.
How is this different from the newer Civilization games?
Beyond the Sword is a 2007 expansion for a 2005 game, built on stacked units and a commerce slider rather than the district and one unit per tile systems of the later entries. Corporations, the espionage slider and Apostolic Palace voting are specific to this expansion and have no direct equivalent in the modern games.
