The document summarizes the ancient West African city of Jenne-Jeno, which was excavated in 1977. Jenne-Jeno was built in the 3rd century BCE and existed for over 1,600 years, proving theories about the lack of early cities in West Africa wrong. It was located at the convergence of the Niger and Bani Rivers, ideal for farming, fishing, and trade. Jenne-Jeno grew to a city of 20,000 people surrounded by walls for status and trade control. Blacksmiths had high status and responsibilities as political leaders, judges, and doctors, due to beliefs in their supernatural powers.
