Unit EditGenghis Khan is a cavalry archer hero available only in the Scenario Editor and the Crucible scenario of his campaign, where he cannot be controlled by the player. Genghis Khan is portrayed as a Mangudai but is much stronger in overall statistics. He is one of the strongest heroes in the game. As a hero, he cannot be converted and can regenerate health (since The Conquerors).
- In old patches (until 1.0b/1.0e) in the campaign scenario Crucible, there is a small chance that Genghis Khan's troops will push his unit into the conversion zone of the player's initial troops, causing him to be controllable by the player and making the scenario ridiculously easy.
- Genghis Khan is a title of uncertain etymology. Proposals include "Ocean-like / Wide spreading ruler" and "Upright Ruler".
- Genghis Khan's birth name, Temujin, is Mongolian for Blacksmith - or more literally, "iron worker" (Proto-Turkic *temü(r)) + Mongolic occupational derivational suffix -cin.
"The nomadic tribes of the Asian steppes spent centuries entangled in their own petty feuds until united under Genghis Khan. Within years, a highly disciplined army pours out of Mongolia to embark on a campaign of world conquest. But how can a tribe of horse archers possibly overcome the military might of Persia and Eastern Europe, let alone the technologically advanced empires in China?"—In-game campaign description
The Genghis Khan campaign consists of 6 scenarios. The player plays as the Mongols, and the player color is orange.
The campaign is narrated by the anonymous author of The Secret History of the Mongols, the main primary Mongolian source in the life of Genghis Khan and the history of the Mongols before and during his reign.
- Genghis Khan is one of only two The Age of Kings characters with the distinction of appearing in the campaign of two different Age of Empires games, the other being Joan of Arc.
- In the DS version, Genghis Khan is a hero unit who accompanies the player throughout the entire campaign. His abilities include Nomadic Travel, Overwhelming Siege, Mongol Terror and Patron of the Arts.
- Prior to the Vietnamese changing architecture in the Definitive Edition, this was the only non-anthology campaign where the player controls a civilization with the East Asian building set.
- Of all campaigns in The Age of Kings, the Genghis Khan campaign was the first decided during development. A version is already described in the fifth Design Document of Ensemble Studios (dated 17 July 1998), although with some notable differences, like the lack of an equivalent to The Horde Rides West, more scenarios set in China, and a final allohistorical scenario in which the player has to conquer Western Europe.
- In the Spanish version, the name Tayichi'uds is translated as "Tajikistanos" (Tajikistanis). However, the Tajiks are actually a Persian-speaking people and therefore unrelated to the Tayichi'uds, who were a Mongol tribe.
