INDIAN HISTORY

Detailed explanation-1: -The early use of iron may have developed from the practice of copper-smelting.

Detailed explanation-2: -These people were called the Aryans. They were skilled warriors who used advanced iron weapons to take control of the entire Indus valley.

Detailed explanation-3: -The main factor in the expansion of the Aryan culture during the later Vedic period was the beginning of the use of iron around 1000 BC. The Rigvedic people knew of a metal called ayas which was either copper or bronze.
