Ancient China developed in isolation due to its geography. The Xia Dynasty was the first to rule in 2200 BC, followed by the Shang Dynasty in the 1500s BC which established a monarchy. The Shang developed innovations like the first writing system with over 2000 symbols, oracle bones for divination, and bronze metallurgy. The Zhou overthrew the Shang in the 1100s BC based on the Mandate of Heaven, establishing a feudal system where the king granted lands to lords in exchange for loyalty and military support.
