How did the Zhou dynasty begin

Started from the Zhou clan

Explanation:

The Zhou Dynasty originated from the Zhou clan whose existence stretches back into history. By the 11th Century BC, this clan had become increasingly powerful and had extended throughout the present Shaanxi and Gansu Provinces. The Clan's mightiness increasingly menaced the Shang Dynasty and the conflict between the two groups intensified.

At that time, the Shang was under the rule of King Zhou. He was atrocious to his people and doted on his imperial concubine, Daji. All he did caused great rage amongst his people. The chief of the Zhou Tribe, Wenwang thought it was the right time to attack the Shang and entrusted his son Ji Fa to fulfill his last wish. After Wenwang died, his son Ji Fa (Wuwang) succeeded him. He made full preparations for the war and killed King Zhou. Thus the Shang Dynasty ended in 1046 BC.
