Spread of a Faith
Click to plant a faith's founding city, then watch it spread outward — leaping fastest along dashed trade routes and rivers, and converting people most readily where believers already live. Turn on a rival faith or a mountain barrier and see how geography and competition reshape who ends up believing what.

What to try
- Found the faith at an inland city versus a port on a trade route. Which spreads faster, and why does the sea route matter?
- Turn the conversion rate right down. Does the faith still reach the far coast, or does distance stall it?
- Raise the missionary reach. How does letting believers influence farther-away regions change the shape of the spread?
- Switch on a rival faith. Where does the boundary between the two settle — and can you move your origin to win a contested region?
- Drop a mountain barrier across the land. Which regions stay unconverted the longest, and does a river or route punch through it?
