The built-up area of Enugu comprised these two areas, and by 1917 the city officially gained township status.
On the African side of the city a rapid influx of migrant workers sparked the development of squatter camps on the Udi Hills near the coal mines and the Iva Valley.
Enugu is also one of the filming locations for directors of the Nigerian movie industry, dubbed "Nollywood".
Enugu's main airport is the Akanu Ibiam International Airport.
Much of the escarpment stretching from Enugu to Orlu has been ravaged by soil and gully erosion.The Hausa traders provided horses to the Nike which were used for rituals by the Igbo.Both the Aro and Hausa migrated back and forth to what is now the city of Enugu and were considered foreigners to the area.The massacre that came to be known as "The Iva Valley Shooting" "Zikisim" was a post World War II movement that was created out of admiration for Nnamdi Azikiwe who was a prominent nationalist of the National Council of Nigeria and the Cameroons (NCNC).The shooting was right after a period of unrest when miners were angered by the belief that their full pay was being held back by the colliery management, a belief that was pushed by the nationalist press.
Many of the Zikists tried to use the Iva Valley shooting to fuel their nationalistic agenda and push the British imperial administration, out of Nigeria.
