Brass River Brass River The Brass River is one of the branches of the Nun River, which in turn is a branch of the Niger River, in the Niger Delta in Nigeria. In the 19th century the river was an important trading route, first for slaves and later for palm oil. Brass River Crude Oil is named for a refinery on the river. The name "Brass" is European, said to have been given to the Nembe coastal villages because they traded for brass pans and neptunes to use for salt boiling. The "Brass Ijo" were all the Ijaw people from Cape Formosa
Nun River Nun River The Nun River is a river in Rivers State, Nigeria. The Nun is formed when the Niger River splits in two, forming the Nun and Forcados rivers. Upon emerging from its parent river, Niger, the Nun River flows for almost south to the Gulf of Guinea at Akassa. Its course runs mainly through thinly settled areas and swamps. In the 19th century, the Nun was a hub for trade between the Igbo Kingdom, which was based at Aboh, and Europe. The river's trading history began with the trade of slaves but was later replaced by palm oil export.
