Il giovane Chinggis Khan ha dovuto affrontare difficoltà dopo che la sua famiglia ha perso il potere. È sopravvissuto alle minacce delle tribù rivali e ha costruito le prime alleanze man mano che diventava un guerriero.
When a neighboring empire attacks one of Chinggis Khan's envoys, he unleashes a campaign that annihilates the empire and solidifies Mongol dominance in Persia.
After Chinggis Khan's secret burial, his son Ogedei is proclaimed the ruler of the Mongol Empire. Ogedai conquers more land, builds a capital, and sets up a campaign against the Kievan Rus.
The Mongolian empire launches campaigns through Russia and Europe but news of Ogedai's death halts the advance and triggers struggles for succession over the largest empire in the world.
