Nigerians or the Nigerian people are citizens of Nigeria or people with ancestry from Nigeria. The name Nigeria was derived from the Niger River running through the country. This name was allegedly coined in the late 19th century by British journalist Flora Shaw, who later married Baron Frederick Lugard, a British colonial administrator. Nigeria is composed of various ethnic groups and cultures and the term Nigerian refers to a citizenship-based civic nationality. Nigerians are derived from over 250 ethno-linguistic groups. Though there are multiple ethnic groups in Nigeria, economic factors result in significant mobility of Nigerians of multiple ethnic and religious backgrounds to reside in territories in Nigeria that are outside their ethnic or religious background, resulting in the mixing of the various ethnic and religious groups, especially in Nigeria's cities. The English language is the lingua franca of Nigerians. Nigeria is divided roughly in half between Muslims, who live mostly in the north, and Christians, who live mostly in the south; indigenous religions, such as those native to the Igbo and Yoruba ethnicities, are in the minority.

The Kingdom of Benin, also known as the Edo Kingdom or Benin Kingdom, is a kingdom within what is now southern Nigeria. It has no historical relation to the modern republic of Benin, which was known as Dahomey from the 17th century until 1975. The Kingdom of Benin's capital was Edo, now known as Benin City in Edo State, Nigeria. The Benin Kingdom was "one of the oldest and most developed states in the coastal hinterland of West Africa". It grew out of the previous Edo Kingdom of Igodomigodo around the 11th century AD, and lasted until it was annexed by the British Empire in 1897.
