The Three Kingdoms era began in 220 AD. After the Han dynasty fell, three powerful states began a war for power and control over China. The three states were the Wu state, Wei state, and Shu-Han state. The three main leaders during this war was Cao Pi of the Wei State, Liu Bei of the Shu-han state, and Sun Quan, the son of Sun Jian of the Wu state. These three people were the kings of their states. The states fought until 273 AD. By that time, the main leaders who started the war were dead and the Jin Dynasty took over China.
