Era of Disunity--Three Kingdoms
The collapse of the Han dynasty was followed by nearly four
centuries of rule by warlords. The age of civil wars and disunity
began with the era of the Three Kingdoms (Wei, Shu, and Wu,
which had overlapping reigns during the period A.D. 220-80).
In later times, fiction and drama greatly romanticized the reputed
chivalry of this period.
