Fall of the Shang Dynasty

The last of the Shang kings was dominated by women, giving up to sensual self-indulgence with his 'pools of wine and forest of meat,' oppressing people with his taxes, craving open pregnant women to examine the fetus, and killing or imprisoning all who remonstrated against him.

King wu launched an attack on the Shang empire in 1120 BCE. This attack was not suceesful. But the second attack ( which is 2 years later) was successful, and the armies of King Wu invaded and sacked Yin, capital of Shang dynasty.

The last Shang king, commited suicide after his army defeated by the Zhou people. There are legends saythat his army betrayed himby joining the Zhou rebels in a decisive battle that took place.
