A federal republic of 36 states and the Federal Capital Territory, Nigeria is the most populous country in Africa. The modern state dates from the completion of the British conquest at the start of the 20th century. Nigeria - the name comes from the River Niger - is made up of 250 ethnic groups, the largest of which are the Hausa, Igbo, Yoruba and Fulani. Over 500 languages are spoken, with English the official language. There are three tiers of government: federal, state and local.
Under the constitution the people considered indigenous to a state have rights such as access to land, resources and political power, that are not granted to settlers. This inequality is a contributory factor in much of the communal strife.
Officially a secular democratic Country 1.), Nigeria is one of a handful of non-Muslim majority countries to belong to the Organisation of Islamic Cooperation (OIC), which describes itself as the “collective voice of the Muslim world”.
Religion plays a very important part in Nigerian life. In statistical terms, the population of 203 million is approximately 49% Christian and 49% Muslim. 2.) The north of the country is predominantly Muslim while the southern states are mainly Christian. A minority of the population practises traditional religions. There is a religious revival underway in the country: Islam has experienced a resurgence in recent decades and the Christian population has also grown explosively over the past century.
The majority Muslim ethnic groups are the Hausa, Fulani and Kanuri. The vast majority of Muslims are Sunni but there is also a significant Shi’ite minority. Nine northern states have incorporated Sharia law into their previously secular legal systems since 1999 while three have instituted it in part. 3.)
The Christian population is roughly three-quarters Protestant and one quarter Catholic with Pentecostal and African churches growing fast. Mostly Christian peoples include the Igbo and Ijaw.
Executive power is exercised by the president who is both the head of state and of government. The current president is Muhammadu Buhari, a Muslim and Fulani, who came to power in 2015.
The two major political parties are the centre-right People’s Democratic Party of Nigeria (PDP) and the centre-left All Progressives Congress (APC). The APC won the general elections in 2015 with a campaign promise to put down the insurgency in the northeast and bring peace to the Middle Belt. Despite largely failing to realise this promise, Buhari was re-elected for a second term in February 2019.
