Kaduna, town, capital ofKaduna state, north-central Nigeria. It lies along the Kaduna River, which is a major tributary of the Niger River. Sir Frederick (later Lord) Lugard, the first British governor of Northern Nigeria, selected the present site along the Lagos-Kano Railway for a town, and building began in 1913. In 1917 Kaduna (a Hausa word for “crocodiles”) replaced Zungeru, 100 miles (160 km) west-southwest, as the capital of the Northern Provinces; it also served as capital of the Northern Region from 1954 to 1967. Lugard Hall, the legislative assembly building constructed in simplified Isl?mic style, stands at the head of the main street. The assassination in Kaduna of Sir Ahmadu Bello, sardauna (sultan) of Sokoto and northern premier, in an Igbo (Ibo) military coup in January 1966 led to the Nigerian civil war (1967–70).
Since the late 1950s, Kaduna has become a major industrial, commercial, and financial centre for the northern states of Nigeria. It has a branch of the Nigerian Stock Exchange. Most industries are grouped south of the Kaduna River near the main railway junction. The town’s cotton-textile spinning and weaving mills are Nigeria’s largest and among the largest in Africa; knit fabrics are also produced in Kaduna. The food industry produces beer, soft drinks, baked goods, and processed meat. Light manufactures include leather goods, plastics, ceramics, pharmaceuticals, furniture, and televisions; and there are several printing and publishing firms. The town’s heavy industries make steel and aluminum products, cement, asbestos cement, concrete blocks, electrical motors, ordnance, and explosives. There are a steel-rolling plant, an automobile assembly factory, and an oil refinery (supplied by a 377-mile- [607-km-] long oil pipeline from the Niger delta oil fields). A petrochemicals plant began operations in the early 1980s.
Kaduna is also a centre for the construction industry. The town serves as a collecting point for cotton, peanuts (groundnuts), shea nuts, and hides and skins; there is also a considerable local trade in sorghum, millet, corn (maize), kola nuts, goats, poultry, and cattle. The government’s Livestock Services Training Centre with headquarters at Kaduna serves the stock-raising enterprises of the northern states.
The Kaduna Polytechnic college (1968) and the Nigerian Defense Academy are located in the town; it also is the site of Christian teacher-training colleges and the Kaduna State Library. The Geological Survey of Nigeria (1930) has its headquarters there, and a geology museum is found in Kaduna. The National Museum, also located there, features exhibitions on the culture of the northern Nigerian states. Kaduna has a racecourse and the Ahmadu Bello Stadium (1964). The Nigerian Institute for Trypanosomiasis (sleeping sickness) Research (1961) and the National Eye Centre are located in Kaduna.
The trunk railways from Lagos, Port Harcourt, and Zaria form a junction in the southern part of Kaduna, and the Lagos-Kano highway passes through the town. There is also an airport 5 miles (8 km) north of the town. Pop. (2005 est.) 1,375,000.
