How To Win A Religious Victory In Civilization VI (Civ 6)
A Player wins a Religion Victory (or “Religious Victory” more accurately) in Civ 6 by making the Religion of that Player’s Civilization the dominant Religion for every other Civilization in the game (in terms of game mechanics, religious dominance means a majority of a Civilization’s cities follow one particular Religion). Conversely, one way to prevent another Civilization from achieving a Religious Victory (and thus the game) is at least preventing its Religion from coming to dominate your Civilization.
While your Religion will spread naturally with the spread of your Civilization as a whole, the religious units Missionaries and Apostles will help ensure a Religious Victory (or at least prevent a Religious Defeat).
To win a Team Religious Victory, the Religions founded by the Team’s individual Civilizations combined together dominate every other Civilization.
