Hausa Kingdoms
Modern Kaduna State is home to the sites of some of Africa's oldest civilizations, including the Nok civilization that prospered from c. 1500 BC to c. 500 AD. In the 9th century, geographer and historian Ya'qubi documented the existence of the Hausa Kingdoms, which existed until the region was incorporated into the Sokoto Caliphate in the early 1800s following the Fulani War. During the colonial era, the city of Kaduna was made the capital of Northern Nigeria Protectorate by British leadership.
