Most of sub-Saharan Africa moved from the Stone Age to the Iron Age. The Iron Age and Bronze Age occurred simultaneously. North Africa and the Nile Valley imported its iron technology from the Near East and followed the Near Eastern pattern of development from the Bronze Age to the Iron Age.
Many Africanists accept an independent development of the use of iron in Sub-Saharan Africa. Among archaeologists, it is a debatable issue. The earliest dating of iron in sub-Saharan Africa is 2500 BCE at Egaro, west of Termit, making it contemporary with iron smelting in the Middle East. The Egaro date is debatable with archaeologists, due to the method used to attain it. The Termit date of 1500 BCE is widely accepted. Iron at the site of Lejja, Nigeria, has been radiocarbon dated to approximately 2000 BC. Iron use, in smelting and forging for tools, appears in West Africa by 1200 BCE, making it one of the first places for the birth of the Iron Age. Before the 19th century, African methods of extracting iron were employed in Brazil, until more advanced European methods were instituted.
Iron metallurgy in Africa. The topic of early iron metallurgy in sub-Saharan Africa encompasses both studies of the technology and archaeology of indigenous iron production, and also an understanding of the role that iron production played in African societies before European colonization.
