Unique technology

Unique technologies are technologies introduced in Age of Empires II: The Conquerors that are unique to a civilization and can be researched at the Castle. In The Conquerors, every civilizations but the Goths (who had two) had access to exactly one unique technology. From The Forgotten and onwards, every civilization has access to two unique technologies, one in the Castle Age and one in the Imperial Age. These technologies typically benefit one or more aspects of that civilization's characteristics and unique units.

Unique technologies can be disabled in favor of additional abilities and units via the "Full Tech Tree" option, thus granting a civilization access to contents that they normally cannot utilize (e.g. Native American civilizations can build Stables and train cavalry) at the cost of their characteristic upgrades that usually benefit their original playing style.

Note that unique technologies also feature in Age of Mythology and Age of Empires III. They are much more common in these games and thus are dealt with in the respective technology articles.
