The Yoruba are a large ethnic group from Nigeria. There are approximately 40 million people of this ethnicity. They make up about 20% of Nigeria's population and there are significant numbers found throughout that part of Africa. They are also one of the most urbanized people on the continent, having formed cities centuries before the arrival of European colonizers.
To say the Yoruba has a rich mythology would be an understatement. They also have a strong artistic style, which was generally considered more "realistic" than other art forms on the continent. They used a lot of art in their formal proceedings, particularly when it involved royalty. This piece is a crown used in ceremonies by a king from Nigeria.
