The Mongols are a playable civilization, led by Genghis Khan. The Mongols were a powerful civilization in real life, having conquered much of the super continent of Eurasia in the 1200s.
In Civilization I, their expansionist outlook makes them the most dangerous of all foes, especially in early to mid-game. On Earth however, their early expansion is hindered by their starting point in mid-Asia, among plains, desert and mountains.
