Emperor of Wei in the Three Kingdoms Period: Cao Cao; Emperor of the Han Dynasty in the Three Kingdoms Period: Liu Bei; Sun Quan, Emperor Wu of the Three Kingdoms Period.

The formation of the three kingdoms: after Battle of Red Cliffs, Cao Cao was forced to retreat to the north and rebuild his strength; Sun Quan's influence in the middle and lower reaches of the Yangtze River was consolidated, and Liu Bei got most of the two lakes and later Sichuan. In this way, the forces of the three warlords are evenly matched, but neither side has the conditions to unify the whole country. Cao Cao's son, Cao Pi, was in Luoyang, abolishing the Han emperor and calling himself the emperor. Liu Bei and Sun Quan also proclaimed themselves emperors. The tripartite confrontation between the three countries has taken shape.
