Ghenghis Khan, is a 1987 turn-based strategy game developed by Koei.

The game takes the player inside the virtual life of either Genghis Khan or one of his archrivals. The player must arrange marriages, father children, appoint family members to governmental positions, and fight in order to conquer the Old World. Armies must be drafted and soldiers must be trained if the player is to rule the lands from England to Japan.

The game has two different ways to play. The first is Mongol Conquest, which begins in the year 1175 A.D, which is a one player mode. Players assume control of Lord Temujin and they must conquer the land by keeping their economy stable, having their army ready to fight, and by attacking other lands. The second is World Conquest, where the goal is to conquer every opposing country.
