The Shang Dynasty has been dated back to 1766 BCE to 1122 BCE. But according to more recent archaeological work it has been place in 1600 BCE to 1046 BCE.
King Tang was the first Shang Dynasty king. He overthrew Jie (leader of the Xia Dynasty)
Mainly a farming society.
Their main crops were a variety of cereals- barley, wheat, rice, and millet. They also grew nuts, fruits, and vegetables.
King Tang started the Shang Dynasty near a nice, clean river that had fertile soil, so they could have good crops. The river was called the Yellow River Valley.
Millet was the main crop in Northern China. While rice and wheat are more known in Southern China.
The Shang Dynasty also raised cows, oxens, pigs, sheep, and other livestock. They domesticated pigs, dogs, sheep, oxen, and silkworms.
The farmers were the largest social class during this time.
Stone axes, harvesting knives, wooden digging sticks, wooden plows, stone sickles, and stone shovels were used.
The farmers used simple, wooden and stone tools to help with the farming.
Besides the fact of their farming, the Shang Dynasty had a great military system, and they were always winning wars. But due to their weakened army (from all the wars) and King Zhou's drinking, and not ruling correctly.
So the Zhou Dynasty overthrew the Shang Dynasty. The Zhou Dynasty started shortly after that.
The Zhou Dynasty overthrew the Shang, because the Zhou believed that the Shang King was evil and heaven no longer wanted him to rule.
