The people of Nigeria have an extensive history. Archaeological evidence shows that human habitation of the area dates back to at least 9000 BCE. The area around the Benue and Cross River is thought to be the original homeland of the Bantu migrants who spread across most of central and southern Africa in waves between the 1st millennium BCE and the 2nd millennium. The name Nigeria was taken from the Niger River running through the country. This name was coined by Flora Shaw, the future wife of Baron Lugard, a British colonial administrator, in the late 19th century.
