Religious Victory Guide (Civ 6): Convert the World

Religious Victory is the only win condition in Civilization VI where your army is made of units that can't capture a single city. You win when your religion is the predominant religion of every surviving major civilization — meaning more than 50% of each civ's cities (not population) follow it. City-states don't need converting, and the count is per civilization, so a two-city rival is a two-conversion job while a sprawling empire is a war of attrition. One hard rule to know up front: while a Religious Emergency is active, you cannot win, even if the conditions are met.

This guide walks the full arc — founding a religion before the cap fills, the four religious units and what they actually do, apostle promotions, the pressure math behind conversion, theological combat, belief selection, and both the offensive and defensive game plans.

Quick Facts

City-states	Do not need converting
Key units	Missionary, Apostle, Inquisitor, Guru — bought with Faith
Key mechanic	Theological combat (apostles vs apostles) decides religious wars
Blocked by	An active Religious Emergency
DLC required	None — Religious Victory is in the base game

Founding a Religion: The Race Against the Cap

Step 1: The Pantheon

A Pantheon costs 25 Faith and exists independently of any religion — foreign religions converting your cities never overwrite it. Grab one early; it's cheap and permanent.

Step 2: The Great Prophet

Founding requires a Pantheon plus a Great Prophet, activated at a Holy Site or Stonehenge. That city becomes your religion's Holy City — a title that matters all game (your Holy City exerts 4× passive pressure and gives defenders +15 theological strength).

Great Prophet points come mostly from Holy Sites; rush a Shrine and run the Holy Site Prayers project to accelerate. You can also land a Prophet without a Holy Site at all — Stonehenge grants one directly, and sources like the Revelation policy card or the Rise and Fall golden-age dedication Exodus of the Evangelists generate points. Once you have your Prophet, leftover points convert to Faith at 1:1, and no second Prophet is possible.

Step 3: Know the Cap — and Who's Racing You

The number of religions allowed is fixed by map size:

Map	Duel	Tiny	Small	Standard	Large	Huge
Max religions	2	3	4	5	6	7

The rule is half the default player count plus one, and adding extra players in advanced setup does not raise it. If Arabia is in the game, a Prophet slot is reserved for them even if they're eliminated. Once the cap is hit, no more Prophets exist — and the Revelation card becomes dead weight.

The AI telegraphs the race: Gandhi, Philip II, Saladin, and Jadwiga beeline early religions (Peter often joins via the Lavra), while Gilgamesh, Gorgo, Pericles, Qin Shi Huang, Trajan, Teddy Roosevelt, Victoria, Alexander, and John Curtin mostly ignore religion entirely. On a Standard map against two religious AIs, you have real but limited time; against four, build the Holy Site in your first three cities or accept you'll be importing a religion.

The Religious Units

Religious units are bought with Faith in cities that have a Holy Site and a majority religion — and the unit you get belongs to whatever religion is dominant at the moment of purchase. If your Holy Site city gets converted, it starts printing the enemy's apostles. Prices rise with every purchase; the Theocracy government's Faith-purchase discount is the only way to lower them.

Unit	Base Faith cost	Religious Strength	Moves	Charges	Requires	Key traits
Missionary	100	100	4	3 Spreads	Shrine	Cannot initiate combat (defense only); ignores borders; spread pressure = 2× current HP; wipes 10% of other religions' pressure in the target city
Apostle	400	110	4	3 Spreads	Temple	Can initiate theological combat; gains 1 promotion on purchase; ignores borders; spread pressure = 2.2× current HP (see note below); wipes 25% of rival pressure
Inquisitor	100	70 / 75	4	3 Remove Heresy	Temple + an Apostle has used Launch Inquisition	Can initiate combat; needs Open Borders to enter foreign territory; +35 RS in friendly territory; Remove Heresy strips 75% of foreign religions (100% for Spain); 4 charges under Philip II
Guru	Not listed in source	—	4	Heal charges (up to 6 adjacent units at once)	Temple	Battlefield medic for religious units

Two data conflicts in the source, quoted as they stand: the Inquisitor's Religious Strength is listed as 70 in the Inquisitor page infobox and 75 in the Religion page's strategy section — check your game version. Similarly, the Missionary page gives spread pressure as 2× current HP while the Apostle page's formula reads 2.2× current HP for apostles — both are recorded here; either way, the practical lesson is identical: never spread with a wounded unit, because spread strength scales with current HP. (The pressure-wipe percentages — 10% and 25% — are unaffected by damage, but note they don't touch atheist pressure; high-population cities full of atheists are genuinely harder to flip.)

The Apostle's Two Secret Powers

Beyond spreading, apostles carry two one-shot abilities:

• Evangelize Belief — adds a belief to your religion (up to 4 total). Consumes the apostle; requires 3+ spreads remaining and friendly territory.
• Launch Inquisition — a global one-time unlock of Inquisitors. Consumes the apostle; requires 3+ spreads remaining.

An apostle that spends its last spread disappears — so plan promotion picks and evangelize timing before the final charge.

Apostle Promotions: The Nine Choices

Apostles roll a random choice of three promotions on purchase; if you're Suzerain of Yerevan, you pick from the full pool, which is a large part of why Yerevan is the best religious city-state in the game.

Promotion	Effect
Chaplain	Acts as a Medic, healing units within 1 tile
Debater	+20 RS in theological combat
Heathen Conversion	Spend a spread to convert all adjacent barbarians
Indulgence Vendor	100 Gold the first time this unit converts a city
Martyr	Generates a Relic if killed in theological combat
Orator	+2 spreads
Pilgrim	+3 spreads the first time it moves adjacent to a natural wonder
Proselytizer	Spread also erases 75% of rival pressure in the target
Translator	Spread strength ×3 in other civilizations' cities (city-states included)

The golden offensive combination is Translator + Proselytizer (triple strength plus pressure wipe) and Debater for your combat line. Orator and Pilgrim stretch charges: base 3 spreads + Mosque 1 + Orator 2 + Pilgrim 3 + Hagia Sophia 1 stacks to 8 spreads (up to 10 in Rise and Fall when Moksha's Patron Saint title grants a second promotion — the only legal route to a three-promotion apostle, stacking with Mont St. Michel's free Martyr for every apostle, applied retroactively).

How Conversion Actually Works: The Pressure Math

Every city tracks pressure from each religion plus atheism. Followers of a religion = population × that religion's pressure ÷ total pressure (rounded). A religion becomes predominant when it holds a majority of citizens. Key rules:

• Each population growth adds +50 pressure to the city's majority religion (or to atheism/pantheon if none — and atheist pressure never goes away).
• Population loss doesn't reduce existing pressures.
• Passive pressure reaches 10 tiles: 1 base from a city with a majority religion, ×2 if it has a Holy Site, ×4 if it's the religion's Holy City (multiplicative — a Holy City with a Holy Site radiates 8). Trade routes from religious cities add 0.5/turn. Passive pressure matters early and then fades; the Wiki is explicit that you cannot win on passive pressure alone.
• Active spreading is the real engine: Missionary/Apostle spreads adjacent to a city, with strength scaling off current HP (see the formula note above) plus the pressure-wipe percentages.
• Non-unit conversion levers exist: Rock Bands with the Religious Rock promotion flip a city's majority religion; Warrior Monks with Disciples apply pressure on kills; and civ abilities — Byzantium's Taxis, India's Dharma, Spain's Conquistadors, Jadwiga's culture bombs — all convert through warfare.
• Rise and Fall loyalty: cities following your religion get +3 Loyalty; those that don't get −3.

Theological Combat: The Rules of the Holy War

Only apostles and inquisitors initiate theological combat; missionaries and gurus can only defend. The essentials:

• Attacking requires adjacency and the ability to enter the target tile. Religious units exert zones of control on each other; while engaged, City Centers and Encampments also exert ZOC.
• All religious units move 4. Everyone except inquisitors ignores closed borders.
• Terrain defensive bonuses don't apply (hills and rivers do nothing), though rivers still cost 3 movement to cross; amphibious penalties don't apply.
• Members of a Religious Alliance cannot attack each other, and units of the same religion never fight.
• Flanking and support bonuses apply (added in the Fall 2017 Update).
• Wounded religious units cannot heal in the field — only on a friendly Holy Site or adjacent tile, at 3× that Holy Site's Faith output per turn. Foreign Holy Sites won't heal you. The Guru exists precisely to patch this.

Why Combat Wins Games: The Pressure Blast

Kills in theological combat detonate pressure: every city within 10 tiles gains +250 pressure for the winner's religion and −250 for the loser's. A single well-chosen engagement near a cluster of cities converts more ground than several spreads — which is why religious wars are fought as armies, not missionaries wandering alone. Military units can also Condemn Heretic (requires war, or a World Religion Outcome B resolution): −125 pressure for the victim's religion within 6 tiles, with no gain for the condemner. The Monastic Isolation enhancer belief negates your losses from theological combat defeats entirely.

Stacking Religious Strength

Base RS is 110 for apostles. From there: Theocracy +5, Religious Orders policy +5, Debater promotion +20, a level-2+ Religious Alliance +10, the World Religion resolution +10, defending on friendly religious soil via Holy Ground +5, defending your Holy City's territory +15, inquisitors +35 in your own lands. The full table in the data files runs longer (Philip II, Byzantium's Taxis, the Tagma, Meenakshi Temple gurus, Wars of Religion, Crusade/Defender of the Faith beliefs, forts, flanking, diplomatic-visibility differentials, and the standard wound penalty all apply). The defensive lesson is in the numbers: an inquisitor at home with Theocracy, Religious Orders, and the Inquisition policy card (+15 in friendly territory) is functionally unkillable, which is exactly why attackers must strip home-ground bonuses first.

Beliefs: Building Your Religion

Each religion holds up to 4 beliefs — one each from the Founder, Follower, Worship, and Enhancer pools — all drawn from a shared global pool: once another religion takes a belief, it's gone. Founders choose first, so late religions pick from scraps. You start with two (one Follower mandatory, plus one of your choice) and add two more by sacrificing apostles to Evangelize Belief. Founder and Enhancer beliefs benefit only the founding civ (Kongo under Mvemba a Nzinga excepted); Follower beliefs apply to any city following the religion; Worship beliefs unlock a tier-3 Holy Site building — one per Holy Site, permanent.

The picks that matter most for a victory run:

• Follower: Work Ethic (Holy Sites give production equal to their adjacency) is the economy king; Reliquaries (triple Faith and tourism from Relics) synergizes with Martyr apostles and Mont St. Michel; Feed the World (+3 Food, +2 Housing from Shrines and Temples) grows the cities you'll need.
• Worship: Mosque (+1 spread for Missionaries and Apostles) directly multiplies your conversion engine; the Pagoda (+1 Diplomatic Favor/turn in Gathering Storm) quietly funds a diplomatic backup plan.
• Founder: Tithe (+3 Gold per following city) scales hardest with your own spread; Pilgrimage (+2 Faith per following city) refunds the machine; Cross-Cultural Dialogue and World Church turn followers into science and culture.
• Enhancer: Holy Order (Missionaries and Apostles cost 30% less) is the default pick; Crusade (+10 combat strength near foreign cities following your religion) fuses religious and military victory; Monastic Isolation makes you immune to theological pressure losses; Religious Colonization auto-founds new cities on your religion.

The Offensive Game Plan

1. Faith per turn is your scoreboard — the Wiki's rule of thumb is that your Faith/turn should roughly equal the number of turns elapsed on Standard speed.
2. Court Jerusalem and Yerevan with envoys; Yerevan's Suzerainty (full promotion pool) enables the Translator/Proselytizer/Debater dream team.
3. Apostles over missionaries. Send missionaries to uncontested backwaters; apostles go where the fighting is.
4. Spend an apostle's last charge only to finish off a religion or to fire a Proselytizer spread; otherwise keep it as a combat piece.
5. Move in packs for flanking bonuses, and bring one Guru — a single heal charge restores up to six surrounding units.
6. Prioritize converting cities with Holy Sites — you cut off the enemy's unit production. A religion whose units are annihilated cannot be revived.
7. Convert the ground you'll fight on first: Holy Ground (+5) and Holy City (+15) bonuses apply to defenders, so don't let enemy inquisitors (75 base, +35 at home) fight you on their terms — pull them out or overwhelm them.
8. High-population cities are harder to flip; when you're not trying to exterminate a religion, take the small cities first. And watch the backfire rule: if a civ with one converted city settles a fresh religionless city, you lose your majority there and must go back.

The Defensive Game Plan

1. Keep a religion of your own (founded or imported) plus 3–4 inquisitors at home for cleansing duty — imported religions can only buy inquisitors after the founder launches an Inquisition.
2. Fight invading apostles in theological combat and rotate wounded units to a Holy Site to heal. Expect AI stacks of 4–5 apostles backed by Theocracy and Religious Orders; remember your defensive bonuses near friendly religious cities.
3. At war, Condemn Heretic with military units — free, repeatable pressure removal.
4. Grow your cities tall: bigger populations are mathematically harder to convert, a natural fit for food-rich civs like Gandhi's India or the Khmer.

Common Mistakes

1. Spreading with wounded units. Spread strength scales with current HP — heal first.
2. Letting your Holy Site city get converted. It will start producing the enemy's religious units.
3. Fighting inquisitors on their home turf. +35 RS in friendly territory; drag them out or ignore them.
4. Relying on passive pressure. It wins the early game and nothing else.
5. Ignoring the religion cap. On smaller maps, two fast AIs can close the founding window entirely.
6. Leaving religious units exposed to military Condemn Heretic range — escort them.

Recommended Civilizations

Per the Wiki's Victory page: Russia (tundra Faith engine), India (powerful missionaries), Spain (Mission Faith plus stronger religious units), Poland (culture-bomb conversion), and Byzantium (fast founding paired with conquest-driven conversion).
