Nigeria

The territory of present-day Nigeria has been inhabited for several millennia, with the Nok culture of the central Jos Plateau, dated to roughly 1500 BCE through the early centuries CE, producing the region's earliest known terracotta sculpture and providing some of the oldest evidence of iron smelting in sub-Saharan Africa. From around the ninth century, the city-state of Igbo-Ukwu in the southeast worked bronze of remarkable sophistication, while the kingdom of Ife emerged in the southwest as a major Yoruba religious and artistic centre, producing the celebrated naturalistic heads in terracotta and brass between roughly the twelfth and fifteenth centuries. The Kanem-Bornu Empire, centred on Lake Chad, dominated the northeast from the late first millennium and converted to Islam in the eleventh century, while the Hausa city-states of Kano, Katsina, Zaria, and others flourished in the north as commercial hubs on the trans-Saharan trade routes.

The Oyo Empire rose in the seventeenth century to become the dominant Yoruba power, while the Benin Kingdom in the south reached its zenith of artistic and political influence between the fifteenth and seventeenth centuries, trading with Portuguese and later English merchants on the coast. In 1804, the Fulani scholar Usman dan Fodio launched a jihad that overthrew the Hausa kings and established the Sokoto Caliphate, which became one of the largest African states of the nineteenth century and consolidated Islamic rule across much of the north. The Atlantic slave trade reshaped coastal societies for nearly four centuries before British abolition in 1807.

British commercial and military penetration intensified through the nineteenth century, beginning with the annexation of Lagos in 1861 and culminating in the formal proclamation of the Protectorates of Northern and Southern Nigeria, which were amalgamated in 1914 under Governor-General Frederick Lugard. Colonial administration relied heavily on indirect rule, particularly in the north, preserving emirate structures while integrating the territory into the British imperial economy. Nationalist agitation grew after the Second World War under figures such as Nnamdi Azikiwe, Obafemi Awolowo, and Ahmadu Bello, leading to a series of constitutional reforms and to full independence on 1 October 1960. Nigeria became a republic in 1963.

The First Republic collapsed in January 1966 when a military coup ended civilian rule, triggering counter-coups, ethnic violence, and the secession of the southeastern region as the Republic of Biafra. The resulting civil war from 1967 to 1970 ended with Biafra's reincorporation. Military governments dominated the following decades, interrupted by the short-lived Second Republic under Shehu Shagari from 1979 to 1983, with successive regimes led by Yakubu Gowon, Murtala Muhammed, Olusegun Obasanjo, Muhammadu Buhari, Ibrahim Babangida, and Sani Abacha. The annulment of the 1993 election won by Moshood Abiola deepened the political crisis until Abacha's death in 1998 opened the path to transition.

Civilian rule was restored in May 1999 under a new constitution, with Obasanjo returning as elected president. Subsequent transfers of power between Umaru Yar'Adua, Goodluck Jonathan, Buhari, and Bola Tinubu, who took office in 2023, have proceeded through scheduled elections, though the country has continued to face the Boko Haram insurgency in the northeast and broader security challenges. Nigeria today is a federal presidential republic of thirty-six states and the Federal Capital Territory of Abuja, with a bicameral National Assembly and a strong tradition of regional balance in national office.
