Age of Empires Series Wiki

Fanaticism is a technology in Age of Empires that can be researched at the Temple once the Iron Age is reached. It increases the recharge rate of all Priests by 50%, allowing them to convert more units over shorter periods of time. Researching Fanaticism also allows the player to upgrade the Long Swordsmen to Legions.

Fanatism is available to all civilizations except for the Carthaginians, Hittites, Minoans, Sumerians, and Yamato.


Religion evolved to provide a spiritual foundation and understanding to life once humans became sufficiently intelligent to ponder the great terrifying questions of our existence.  A disturbing byproduct of the spread of religion was fanaticism- the intense, unquestioning devotion to the ideas and leadership of other humans.  Fanatics were capable of any act, even at great risk to their lives, and were especially dangerous enemies in war.
