Which technologies trigger enter to next era?

Hello again.

I've got next simple question

Which technologies trigger enter to next era?

Is there any list of these techs?

 

[JujuLautre]

All of them.

Every technology belongs to an era. You enter into the next era when you research your first technology of this era, that's all.
I do not know if there is a list somewhere with eras, perhaps someone could help about that? Otherwise, just look into the Beyond the Sword\Assets\XML\Technologies\CIV4TechInfos.xml file, everything is in there.

if you press f6 you will see the tech tree. If you hover your mouse over a tech you will see the message that you will advance to the next era if that tech will do that.

Ancient to Classical : Iron Working, Metal Casting, Alphabet, Aesthetics, Monarchy, Code of Laws, Mathematics, Horseback Riding.
Classical to Medieval : Machinery, Feudalism, Philosophy, Theology, Civil Service, Music.

Getting any one in each group advances to the new era.
Mind you, the only effects of entering a new era are (a) techs in the new era cost more, and (b) the music changes - except, alas, going from Modern to Future.

The graphics change when you enter the Industrial Era as well.

I've just remembered something else: the points gained per tech also rise by 1 per era, though this only matters if you're concerned with your score.

The Workers change when you enter the Industrial Era as well.

Fixed. The graphics always change when you go to a new era. The only unique change to the Industrial Era is the Workers changing from serfs to union workers.

Also relevant to completing quests in time. Quite often I've deliberately slowed the science slider to zero just to get a few more turns to complete a high-value quest before triggering the next age...

I never noticed that it's possible to go straight from Ancient to Medieval without entering the Classical Era. All you have to do is research or lightbulb Theology, whose prerequisites are all Ancient techs.

For a while, when I was playing the Warlord difficulty, I had no idea there even was a Classical Age.
