People in Africa in the Caucasus regions or people in West Asia called the Hittites (not sure which is right. websites say different stuff) started crafting iron into tools and weapons, replacing the bronze age with the iron age.
The Hittites kept their secret for 400 years until the Dark ages came and the Hittites empire fell apart around 1100 b.c. Then, everyone in the Mediterranean knew about it and started to use iron.
When India was invaded, the invaders brought the knowledge of iron with them and it traveled to India from 700-600 b.c. In 300 A.D., everyone in West Africa and East Africa knew the secret of iron. Iron on the periodic table Symbol Name Atomic mass not on here: group 8,period 4, and group d
