Around 700 B.C., a small civilization emerged in the Niger River Valley known as the Nok People civilization. Very little is known about this people or about their culture. They were not as wealthy as the kingdoms of the North. They led a quiet life of farming and family. The few artifacts that have been found show that they used iron tools to plow and farm the land.
