Introduction of Iron
First we begin with the little bit of history. If we look at the concept of dividing historical ages in term of stone age bronze age and iron age .
In stone age begins with the 2.5 million year ago in Africa that’s where humans evolve than the bronze age begin around 2300 BC and the finally iron age begin somewhere in between 1500 to 1200 BC.
Now I give you rough discription of these ages. In the stone age early man invented and created weapons made up of stone and bone for the survival. It is said that stone age came to in the end sometime after that the end of last ice age.
This time man learn how to mine copper and then to make bronze weapons. That’s when the bronze age comes bronze is a combination of 10% Tin and 90% copper that means miner and craftman’s were need to mine tin and copper. Bronze weapons are much stronger than the stone age weapon. the discovery of branch change many things after the bronze age the iron age arrived. This was the time when people made tools of iron .
Introduction Of Iron In The Indian Subcontinent
In the Indian subcontinent the iron age begin roughly around 1500 to 1200 BC. Now when ever when we think of history concerning the Indian subcontinent the Indus valley civilization concern to your mind right ?
So remember the first point Indus valley civilization (IVC) was a bronze age civilization.
Now coming to the modern era ..
The development of Iron and Steel Industries
Now coming to the modern era the development of industries open the door to the rapid industrial development in India. Almost all sector of the Indian industry depend heavily on the steel industry for the basic infrastructure.
After that TATA Iron steel company (TISCO) was established by Dorabji Tata in 1907 . In 1939 TISCO become the largest steel plant in British era.
