Bronze Age

The Chalcolithic period (or Copper Age) began about 4500 BCE, then the Bronze Age began about 3500 BCE, replacing the Neolithic cultures.

The Indus Valley Civilization (IVC) was a Bronze Age civilization (3300–1300 BCE; mature period 2600–1900 BCE) which was centered mostly in the western part of the Indian Subcontinent; it is considered that an early form of Hinduism was performed during this civilization. Some of the great cities of this civilization include Harappa and Mohenjo-daro. The cause of the destruction of these regions around 1700 BCE is debatable, although evidence suggests it was caused by natural disasters (especially flooding) and Indo-European invaders.[3] These invaders are commonly referred to as the Aryan and their dominance created the Vedic period, which lasted from roughly 1500 BCE to 500 BCE. During this period, the Sanskrit language developed and the Vedas were written, epic hymns that told tales of Aryan gods and wars. This was the basis for the Aryan religion, which would eventually sophisticate and develop into Hindusim, a religion based on the caste system of class (which consisted of the four varnas), the brahman priesthood, and the developing semi-monotheism.[4]

China and Vietnam were also centres of metalworking. Dating back to the Neolithic Age, the first bronze drums, called the Dong Son drums have been uncovered in and around the Red River Delta regions of Vietnam and Southern China. These relate to the prehistoric Dong Son Culture of Vietnam. Song Da bronze drum's surface, Dong Son culture, Vietnam

In Ban Chiang, Thailand (Southeast Asia), bronze artifacts have been discovered dating to 2100 BCE.

In Nyaunggan, Burma bronze tools have been excavated along with ceramics and stone artifacts. Dating is still currently broad (3500–500 BCE).
