Unique technology (Age of Empires II)

This article is about the unique technologies in Age of Empires II. For unique technologies in other games, see unique technology.

Unique technologies are technologies introduced in Age of Empires II: The Conquerors that are available to only one civilization. They can be researched at the Castle. In The Conquerors, every civilizations had access to exactly one unique technology, except the Goths (who had two). Since The Forgotten, every civilization (including those previously introduced) 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 are disabled in the "Full Tech Tree" option.
