The Mongolian Empire took the lands of Russia and Europe, but Ogedei's death triggered a struggle for succession over the largest empire in the world.

Ogedei is proclaimed ruler of the Mongol Empire. He conquers Armenia, Georgia, and the Jin Empire and builds the grand capital of Karakorum.

When an empire attacks the Mongols, Chinggis Khan incites a campaign that solidifies dominance in Persian lands. He names Ogedei as his successor.

Chinggis Khan built power by building an army and eliminating rivals. He began conquests against the Tanguts and the Jin, expanding his empire.

Temujin's powers grow as he battles with Jamuqa. He is exiled, but he returns to unify the Mongol tribes when he takes the title of Chinggis Khan.

Chinggis Khan's early years are recounted, including his family's fall from power, survival against rival tribes, and alliances as a young warrior.
