Guns are a man’s weapon. The introduction of various products from Europe such as gin, guns, and gunpowder created or strengthened any kind of hierarchy that put men over women because only men, by custom, handled these important trade goods.Old and faulty guns were sold to Africans by Europeans.

T. Basden (1921) “Among the Ibos of Nigeria”.Europeans arrived on the shores of the Niger Delta by the end of 15th century.
