Civilization VII · Antiquity Age Maurya India
Maurya India runs an economy built on managed Happiness — deliberately generating a surplus and then converting it into Science or Gold, rather than treating Happiness as just a problem to avoid.
Unique Ability
"Dhamma Thambhā" (the civilization's ability was reworked in the 1.4.0 update from an earlier version called Dhamma Lipi) increases Happiness on Happiness, Military, and Science Buildings, growing further in the Modern Age, and fully heals Land Units when you enter a Celebration. Its Antiquity Age Apex tier converts excess Happiness in Cities into Science, while a later tier converts excess Happiness into Gold instead — letting you choose which yield to prioritize as the game develops.
Unique Unit
The Purabhettarah is a unique Chariot-replacement with +5 Combat Strength against Fortified Districts, at the cost of lower Movement than the standard unit. The Nagarika is a unique Settler that grants +2 Happiness to a new Settlement's City Hall the moment it's founded.
Unique Infrastructure
The Dharamshala and Vihara are Maurya's unique buildings, combining into the Matha Unique Quarter, which adds a Happiness percentage bonus to the whole settlement. The associated Wonder must be placed on a Plains tile, with increased Production toward its construction.
