In Civilization IV, a Golden Age is a sequence of turns in which a civilization gains bonuses to production and can change civics without anarchy. Players often abbreviate Golden Age as GA, which is unfortunately the same abbreviation as is used for Great Artists. Which one is meant should be clear from context.
Triggering a Golden Age Edit
The other way to begin a Golden Age is by using Great People.
- In Beyond the Sword, this requires one Great Person sacrificed for the first Golden Age you trigger using Great People, then 2 Great People, 3 Great People, etc.
- In vanilla and Warlords, the first Golden Age requires two Great People.
They must be of different types. To trigger a Golden Age with Great People, move them together. Then you will see the "Trigger Golden Age" button is active when you select one. You can click it to initiate the Golden Age; note that the effects begin immediately.
A Golden Age lasts for 8 turns (on normal speed), or 12 turns if you own the Mausoleum of Maussollos. Durations on all game speeds are:
Marathon 16 Epic 10 Normal 8 Fast 6
If a second Golden Age is triggered during a Golden Age, additional turns (as per the table above) are added to the ongoing one at the end.
When a civ is in a Golden Age, the following effects apply to it:
- no anarchy: the civ can change civics during a turn without anarchy; that is, it can change civics like it was Spiritual.
- increased commerce: any tile that produces at least 1 commerce will get one bonus commerce. If your civ is Financial, then you get your +1 commerce on all tiles with commerce!
- increased production: any tile that produces at least 1 hammer will get one bonus hammer.
- increased Great Person birthrates: all cities get a +100% bonus to their rate of Great Person point production.
