I wanted a single list of everything that affects happiness. I couldn't find one, so I compiled it myself. If I have some details wrong, please post corrections and I will edit.

HAPPINESS

+X difficulty level

+1 each dye, fur, gems, gold, incense, ivory, silk, silver, spices, sugar, whale, wine
+1 Market per fur, ivory, silk, whale
+1 Forge per gems, gold, silver
+1 Theatre with dye
+1 each Cathedral with incense

+1 hit movies, hit musicals, hit singles
+1 Broadcast Tower (or Eiffel Tower) per hit movies, hit musicals, hit singles

+1 per future tech

+1 each 10% culture
+1 Colosseum per 20% culture
+1 Theatre per 10% culture
+1 Broadcast Tower (or Eiffel Tower) per 10% culture

+1 state religion in city
+1 Palace
+1 each Temple
+2 Cathedral of state religion
+1 Free Religion per religion in city
+1 Colosseum
+1 Notre Dame on continent
+1 Environmentalism per jungle, forest
+1 Hereditary Rule per military unit in city
+2 Nationhood with Barracks
+3 Representation in X largest cities (X=4 to 6, depending on map size)

UNHAPPINESS

+1 each citizen
+1 per 3 citizens, if undefended
+??? war weariness (reduce: 25% Jail, 25% Mt Rushmore, 50% Police State)
+??? cultural inferiority
+1 per slavery used (within last 10 turns, scaled by game speed, or longer if repeated)
+3 per draft used (within last 10 turns, scaled by game speed, or longer if repeated)
+1? each other civ with Emancipation
(Globe Theatre negates all unhappiness)

IIRC, citizens won't complain about being undefended until size 3.

It's something like that, though I think it might be different for each difficulty level.

Also, the amount of people who are unhappy for this problem depends on the city size.

For example, I just tried this with a size 20 City and 6 :eek: people are unhappy.

Req

happiness penalty for undefended cities seems to be 33% of the city size (at noble difficulty). also note that each type of cathedral adds +1 happy for incense, so a city having a cathedral for each religion gets a total of +8. the palace also gives +1 for your capital

You also have Globe Theatre = No unhappiness in the city you build it.

Isn't it +9 for the cathedrals? You get +1 for incense for each of the seven religions, and +2 for your state religion.

You get +1 for incense for each of the seven religions, and +2 for your state religion.well, i was thinking +1 for incense and the seven extra +1 from the cathedrals ;) if you actually get all religions to spread in your empire i think it is better to go free religion for the happiness instead of the religious buildings

Representation is +3 in the 4-6 largest cities (depending on map size).

When I trade resources,e.g., silk for wheat, other civilizations seem to offer what I already have back to me. Do we lose the resource if we trade it?

Do we lose the resource if we trade it?

Yes, unless you have multiple sources.

The slavery unhappiness can last longer than 10 turns if you do slavery multiple times. I've seen -3 penalty for "We cannot forget your creul oppression), and seen it say I'd get -1 for something like 27 turns if I whipped out the current item. I haven't tried to work out the exact formulas though.

I think it also is dependant on game length.
