The word "Kaduna" is thought to be derived from a Gbagyi word for river. Another proposed origin links the name to the Hausa word for crocodile, but this is challenged by the Gbagyi people who are known to have lived in the area for centuries. What is now known as "Kaduna State" is mostly made up of land said to have been inhabited by people of the "Nok" culture. The name "Nok" is derived from the village of Nok in Kaduna, where some of the first major artifacts from the Nok culture were found. The British colonial capital moved from Jebba to Zungeru in 1902, and then to Kaduna in 1916. It is thought that the name Kaduna was taken up by Lord Frederick Lugard and his colleagues during the move to Kaduna.
